A survey reveals that 25 percent of a population of 1,000 individuals have attached earlobes (are homozygous recessive for the t
Mumz [18]

Answer:

d. pxp +2pq

Explanation:

The formula for genotype frequency for a population in Hardy-Weinburg equilibrium is as under:

                           p² + 2pq + q² = 1

where, p = dominant allele

           q = recessive allele

Here,

 p² represents frequency of homozygous dominant genotype

2pq represents frequency of heterozygous genotype

q² represents frequency of homozygous recessive genotype

Also, although the genotypes p² & 2pq are different from each other yet phenotypically they both will collectively produce dominant trait i.e. free ear lobes not attached earlobes. So the term "p² + 2pq or pxp + 2pq" represents the frequency of the individuals who show the dominant phenotype in this particular population. Dominant phenotype will comprise 75% of the population.

A population of trout in a lake has significantly declined over the past year. The main source of food for the fish in this lake
andrew11 [14]

The decline in the overall population of trout and larger fish is because the Insect population has decreased.

<h3>What is a population?</h3>

A population is a group of organisms of the same species living in the same habitat.

Population of organisms is affected by;

  • availability of water
  • space
  • food and nutrients
  • predators
  • climate change

Since the population of trout is directly affected by the number of insect species, the decline in the overall population is because the Insect population has decreased.
