PLS HELP ASAP! BRAINLIEST IF CORRECT!! The trait for flower color in a plant has red and white alleles. The red color is the dominant trait. What is the phenotypic ratio for a cross between plants with red (Rr) flowers and white (rr) flowers?

4 red : 0 white
3 red : 1 white
2 red : 2 white
0 red : 4 white

Answers

Answer 1

Answer:

Its 4 red: 0 white

Explanation:

look at a RrRr punnet square, then it shows the ratio.

R R

r Rr Rr

r Rr Rr

the square shows that all the plants will be red because if a trait is recessive, it needs to be shown in both parents for the offspring to have it. All offspring will carry this trait, but it will not show.

In a recent year, about 22% of Americans 18 years and older are single. What is the probability that in a random sample of 200 Americans 18 or older more than 30 are single? (Hint: use binomial to normal approximation techniques) Round your z-score to 2 decimal places before referencing table E. Then provide answer out to 4 decimal places.

Answers

Using the normal approximation to the binomial, it is found that there is a 0.0107 = 1.07% probability that more than 30 are single.

Normal Probability Distribution

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.The binomial distribution is the probability of x successes on n trials, with p probability of a success on each trial. It can be approximated to the normal distribution with [tex]\mu = np, \sigma = \sqrt{np(1-p)}[/tex].

In this problem, the proportion and the sample size are, respectively, p = 0.22 and n = 200, hence:

[tex]\mu = np = 200(0.22) = 44[/tex]

[tex]\sigma = \sqrt{np(1 - p)} = \sqrt{200(0.22)(0.78)} = 5.8583[/tex]

The probability that more than 30 are single, using continuity correction, is P(X > 30.5), which is 1 subtracted by the p-value of Z when X = 30.5, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{30.5 - 44}{5.8583}[/tex]

Z = -2.3

Z = -2.3 has a p-value of 0.0107.

0.0107 = 1.07% probability that more than 30 are single.
