Answer: C. 82.26%

Explanation:

Given : The red blood cell counts of women are normally distributed with

$\mu=4.577\text{ million cells per microliter}$

$\sigma=0.382\text{ million cells per microliter}$

Let X be the random variable that represents the red blood cell counts of randomly selected woman.

Z-score : $z=\dfrac{X-\mu}{\sigma}$

For X=4.2

$z=\dfrac{4.2-4.577}{0.382}\approx-0.99$

For X=5.4

$z=\dfrac{5.4-4.577}{0.382}\approx2.1544$

Now, the probability that the women have red blood cell counts in the normal range from 4.2 to 5.4 million cells per microliter will be :-

$P(4.2$

Hence, 82.26% of women have red blood cell counts in the normal range from 4.2 to 5.4 million cells per microliter.

Round seeds (R) are dominant to wrinkled seeds (r), and yellow seeds (Y) are dominant to green seeds (y). What is the expected p

asambeis [7]

Answer:

The correct answer would be- 1:1:1:1.

Explanation:

According to the question the cross between the two pea plants with the genotype RrYy and rryy where R for round seeds and r for recessive form that expressed wrinkled seed character. The other character of this dihybrid cross is the color of the seds Y for green and y for yellow seeds.

The cross is shown in the image attached that suggests that phenotypic ratio would be 1:1:1:1 as RrYy, Rryy, rrYy, and rryy.

Thus, the correct answer is : 1:1:1:1.
