A. i think its this because they get their energy from gravity. its originally potential energy as a cloud but as the water droplets condense and collect into rain drops they get heavy and that potential energy is turned into kinetic energy. this isnt up there so A.

Suppose a population is carrying a condition controlled by two alleles: R (dominant) and r (recessive). Only homozygous individu
White raven [17]

<span><u>The answer is A. 72.25 percent.</u>

The Hardy-Weinberg principle can be used:</span>

<em>p² + 2pq + q² = 1</em> and <em>p + q = 1</em>

where <em>p</em> and <em>q</em> are the frequencies of the alleles, and <em>p²</em>, <em>q²</em> and <em>2pq </em>are the frequencies of the genotypes.

<span>The <em>r</em> allele (<em>q</em>) is found in 15% of the population:
q = 15% = 15/100
Thus, q = </span><span>0.15

To calculate the <em>R</em> allele frequency (<em>p</em>), the formula p + q = 1 is used:
If p + q = 1, then p = 1 - q
p = 1 - 0.15
Thus, </span><span>p = 0.85

Knowing the frequency of the <em>R</em> allele (<em>p</em>), it is easy to determine the frequency of the RR genotype (p²):
p² = 0.85² = 0.7225

Expressed in percentage, p² = 72.25%.</span>

Please help I don’t understand this!!! I’ll mark you as brainliest if correct.
Anettt [7]

Answer:

Aa

Explanation:

In Punnett Square, you are bringing the letters on the top to the numbered squares, if that makes sense. It is to predict the genotype of offspring.

So square 1, on the left is A, and on the top is A, so it would be AA.

For square 2, on the left is a, and on the top is A, so it would be Aa.

For square 3, on the left is A, and on the top is A, so it is AA.

Square 4, your question, has a on the left, and A on the top, so it is Aa.

Hope it makes sense. You should probably watch a Punnett Square tutorial online or something for a full and more general explanation.
