Any change in the DNA sequence of a cell. Mutations can be caused by mistakes in cell division or by being exposed to DNA-damaging agents in the environment. Mutations can be harmful, beneficial, or inactive.
Hereditary mutations cause cystic fibrosis, hemophilia, and sickle cell disease. Other mutations can happen on their own during a person's life. These are known as sporadic, spontaneous, or new mutations. They only affect a small number of cells.
Genetic mutations are changes to your DNA sequence that occur during cell division, or when your cells multiply. Your body's DNA coding directs it on how to create and operate. Hereditary mutations can cause genetic disorders like cancer, or they might help people adapt to their surroundings over time.

How do you rule a X-linked recessive pedigree?
Ruling a X-linked recessive pedigree involves analyzing the family history and pattern of inheritance of a trait or disorder to determine if it is likely to be inherited in an X-linked recessive pattern.
The disorder can be identified by:
Construct a pedigree by gathering information about the family history of the trait or disorder. Identify the pattern of inheritance by analyzing the transmission of the trait or disorder within the family. X-linked recessive disorders typically show a pattern of transmission in which affected males are only found in the direct line of descent from a female carrier. If the disorder is only found in males and not females, or if it is found mostly in males, it could be X-linked recessive.Exclude other possible modes of inheritance. Confirm the mode of inheritance by performing genetic testing. Genetic tests such as DNA sequencing or linkage analysis can be used to identify the specific genetic mutation causing the disorder in affected family members. Identify the specific gene mutation. With the help of genetic testing and linkage mapping it's possible to identify the specific gene and the mutation that causes the disorder.To know more about Pedigree analysis, click here,

Don't copy from the internet, If you do, Summarize it into an answer no longer than 2-3 sentences and make it your own words
BIG BRAIN ANSWER:
Before Darwin, a naturalist named Jean-Babtiste Lamarck believed that the environment altered the shape of individuals and that these acquired changes were then inherited. Meanwhile, Charles Darwin was a naturalist on a ship called the HMS Beagle, and he discovered that the beak shape varies among finch species in the Galapagos Islands. He found that the beak of an ancestral species of finch had somehow been transported to these islands, and adapted over time to acquire different food sources that were available, causing variation, and that nature just selected for the most suitable beak shape and against less useful ones.

Transcriptional regulators bind most frequently at the ______ site of DNA. A) major groove. B) minor groove. C) histone complex. D) primary supercoil.
Answer:Major groove
Explanation:
Transcriptional regulators bind most frequently at the major groove of DNA. The major groove is a wider, more accessible groove on the surface of the DNA helix, while the minor groove is narrower and deeper. Transcriptional regulators, which are proteins that bind to DNA and regulate gene expression, often bind to specific sequences of DNA in the major groove to modulate the transcription of particular genes. A histone complex is a group of proteins that helps package the DNA into a compact structure called chromatin, while the primary supercoil is a twisted, spiral structure that forms when DNA is wrapped around histones.

Notch is a receptor protein displayed on the surface of certain cells in developing fruit fly embryos. Notch’s ligand is a membrane-bound protein called Delta that is displayed on the surface of adjacent cells. When Notch is activated by its ligand, the intracellular tail of the Notch protein becomes separated from the rest of the protein. This allows the intracellular tail to move to the cell’s nucleus and alter the expression of specific genes.
Which of the following statements best explains Delta’s role in regulating cell communication through the Notch signaling pathway?
A. Delta transmits a chemical signal to all the cells of a developing embryo.
B. Delta allows the cells of a developing embryo to communicate without making direct contact.
C. Delta restricts cell communication to short distances within a developing embryo.
D. Delta determines which cells in a developing embryo express the gene that encodes the Notch protein.
If Delta is displayed on the surface of adjacent cells, and when Notch is activated by its ligand, the intracellular tail of the Notch protein becomes separated from the rest of the protein and allows the intracellular tail to move to the cell’s nucleus and alter the expression of specific genes, then C.

Is calico an example of Codominance?
Calico is a coat color found in cats that is caused by sex-linked co-dominant alleles.
The calico cat displays a mixed color of red and black, depending on which of her two X chromosomes is inactivated. The allele that codes for orange hair color is dominant, while the black color allele is recessive. In cats, the X chromosome carries the gene that determines coat color, and calico cats have two different versions (or alleles) of this gene. One allele produces orange fur, the other produces black fur.
Codominance actually means that neither allele can block or camouflage the expression of the other allele. Co-dominance can also occur in less obvious traits such as blood type.

What happens to green light when it hits a plant leaf?
Explanation:
When light strikes a leaf, it can be absorbed by, reflected from or transmitted through the leaf. Plants appear green because they reflect and transmit slightly more green light than they do blue or red light. Chlorophyll also absorbs green light poorly. For these reasons, green light is sometimes stated as not being useful to plants for photosynthesis. However, green light is still moderately effective since other pigments absorb the light and make it useful for photosynthesis. A more correct statement is that, generally, green light is less efficient at stimulating photosynthesis than blue or red light. In some situations, the greater reflection and transmittance of green light by leaves can be desirable. Green light can better penetrate a plant canopy and thus reach lower leaves. This can, in theory at least, reduce lower-leaf loss. However, few LED arrays contain green LEDs because they are less efficient than blue and red LEDs from both an electrical and plant response perspective.

Two factors that could affect whether the fly population on the island is in Hardy-Weinberg equilibrium are mutation and selection.
The way in which these two factors would affect, if the population of flies on the island is in Hardy-Weinberg equilibrium would be:
Mutation is a process by which new alleles are introduced into a population, which can alter the distribution of alleles in the population. If a new allele is introduced that provides a fitness advantage, then it could cause the allele frequencies in the population to move away from the Hardy-Weinberg equilibrium.Selection is the process by which certain alleles become more or less common in a population due to their relative fitness advantages or disadvantages. If a particular allele provides a fitness advantage, then the frequency of that allele will increase in the population, causing the population to move away from the Hardy-Weinberg equilibrium. On the other hand, if a particular allele provides a fitness disadvantage, then its frequency will decrease, again causing the population to move away from the Hardy-Weinberg equilibrium.Learn more about Hardy Weinberg equilibrium:

relationship than organisms that share only the same phylum? Explain your reasoning using the results of
your investigation.
The evolutionary relationship is stronger the more similarity. The taxonomical hierarchy's lower levels show more similarity. Thus, the organisms of the same species exhibit the greatest degree of similarity.
What is taxonomical hierarchy's?Taxonomic hierarchy is an organizational structure used to classify or categorize living organisms.
Of course, organisms that belong to the same order will have a closer evolutionary bond than those that belong to the same phylum alone. Taxonomy groups organisms in various ways, as we all are aware. Kingdoms are the highest level of classification, followed by phyla, classes, orders, families, and species. The similarities between organisms will become more specific with each succeeding unit. In other words, when organisms are further subclassified, they share similar traits.
The order of organisms belonging to the same phylum is not required. The class, phylum, and kingdom of any two organisms from the same order, however, will always be the same.
For instance, the cockroach order Blattodea and the human order Primates. These two belong to the phylum chordata. But we are aware of the differences between cockroaches and people.
However, another member of the primate order, such as the monkey and the chimpanzee, have stronger evolutionary ties to humans and share more traits with them.
