In chickens, the allele for feathered legs (F) is dominant over the allele for bare legs (f). In a population of chickens on a f
exis [7]

Answer:

0.5

Explanation:

According to Hardy-Weinberg equilibrium p2+2pq+q2=1 (p+q=1)

p2 is frequency of the dominant homozygous genotype

2pq is the frequency of the heterozygous genotype

q2 is the frequency of the recessive homozygous genotype

In the example above 80 chickens have bare legs (ff)-recessive homozygous which means that the frequency of that genotype is 80/240+80=0.25 (q2), frequency of the recessive allele is\sqrt{0.25}=0.5. This means that the frequency of the dominant allele (p) is 1-0.5=0.5

So, the frequency of the heterozygous genotype (2pq) is 2*0.5*0.5=0.5

The frequency of the dominant homozygous genotype is p2=0.25

How does the predator-prey relationship affect a population?
nika2105 [10]

Answer:

The relationship controls the population size of both species.

(Please vote me Brainliest if this helped!)

Explanation:

A predator-prey relationship tends to keep the populations of both species in balance. This is shown by the graph in Figure below. As the prey population increases, there is more food for predators. So, after a slight lag, the predator population increases as well.
