Red hair is a recessive trait in humans. If 2% of the US population has red hair (q2), then what percent of people in the US are heterozygous (2pq) for this trait assuming that the population is following Hardy-Weinberg equilibrium? Write your answer as a whole number percentage. Do not include decimals or the percent symbol (%).

If 2% of the US population has red hair (q²), then the percent of people in the US are heterozygous (2pq) for this trait at Hardy-Weinberg equilibrium is 24%.

The equation of the Hardy-Weinberg equilibrium is p² + 2pq + q² = 1, where,

In this case,

In consequence the percentage of heterozygous is

2pq = 2 x 0.141 x 0.859 = 0.242 > 24%

In conclusion, if 2% of the US population has red hair (q²), then the percent of people in the US are heterozygous (2pq) for this trait at Hardy-Weinberg equilibrium is 24%.

Explanation:

For Hardy weinberg principle for a population in equilibrum we have,

P2+ 2pq+q2=1

P+q= 1

Given that q2=2%

q2=0.02

q=√0.02

q=0.141

Since p+q=1

Therefore, p=1-q

p=1-0.141

p=0.859

P2=0.737

Since p2+2pq+q2=1

2pq= 2×0.859×0.141

=0.24

0.24×100

2pq=24%

Therefore 2pq will be 24% of the population

the answer is z.

the human body has five levels of organization. level 1: cells. cells are the basic units of life and form the first level of organization. cells in the human body have specific functions. examples include nerve cells, blood cells, liver cells, and so on.
