Mark turned quickly, pivoting on his right foot, while he was playing basketball. He felt a sudden, sharp pain in his knee and f
Contact [7]
<span>The correct answer is that he has injured one of the tendons or ligaments that help keep his knee in place, connecting it to the surrounding muscle and bone. As a result of this injury, his knee is no longer connected to the muscle and bone, thus it wobbled sideways when he started walking. He needs to go to a doctor immediately who can fix his knee so as to prevent further complications - he just needs his knee to be set in place again.</span>

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
