For this question, we will utilize a population of Martians that is in Hardy Weinberg Equilibrium. The dominant Martian phenotyp
Brrunno [24]

Answer:

d.0.48

Explanation:

When a population is in Hardy Weinberg equilibrium the <u>genotypic </u>frequencies are:

freq (AA) = p²

freq (Aa) = 2pq

freq (aa) = q²

<em>p</em> is the frequency of the dominant <em>A</em> allele and <em>q</em> is the frequency of the recessive <em>a</em> allele.

In this population of 100 individuals, 84 martians have the dominant phenotype and 16 have the recessive phenotype.

Therefore:

q²=16/100

q² = 0.16

q=√0.16

q = 0.4

And p+q=1, so:

p = 1 - q

p = 1-0.4

p = 0.6

The frequency of heterozygotes is:

freq (Aa) = 2pq = 2 × 0.4 × 0.6

freq (Aa) = 0.48

Protein recommendations are the daily dietary protein requirements for an individual based on that individual's weight.

<h3>What was the dietary protein requirement?</h3>

For a typical sedentary adult, the suggested dietary allowance is 0.8 grams per kilogram of body weight. For instance, 60 grams of protein should be consumed daily by a person who weighs 165 pounds, or 75 kilograms.

Christine has already ingested half of the 40 grams of dietary protein that her doctor recommended. This indicated that she had already ingested roughly 20 grams of the recommended dietary protein and needed an extra source of protein to meet her daily needs. Christie must therefore have four more servings of snacks to complete her daily protein requirements.
