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.

What contributed to the specification in Darwin's Finch theory
Keith_Richards [23]

Answer:

On his visit to the Galapagos Islands, Charles Darwin discovered several species of finches that varied from island to island, which helped him to develop his theory of natural selection.

Darwin's finches are a classical example of an adaptive radiation. Their common ancestor arrived on the Galapagos about two million years ago. During the time that has passed the Darwin's finches have evolved into 15 recognized species differing in body size, beak shape, song and feeding behaviour.
