Answer:

D. Ecological competition

Explanation:

The small population of finches reached the Galapagos island and established themselves. The geographical isolation of Galapagos islands from each other led to the prevention of interbreeding among the populations of finches present on the separate islands.

The different populations of finches accumulated variations to get adapted to the available food. Accumulation of genetic variations and geographical isolation led to their reproductive isolation from each other.

To get themselves better adapted to the surroundings, the population of finches experienced increased genetic differences between them, that is ecological competition. Repetition of the whole process of the chains of islands led to the evolution of different species of finches.

In a population of rabbits, there are 496 black rabbits and 27 white rabbits. Fur color is determined by a pair of alleles where
Troyanec [42]

Answer:

0.96

Explanation:

It is given that

B is the dominant allele which represents the black color

and b is the recessive allele which represents the white fur.

B being dominant will result into black color fur for genotype "Bb"

Given -

Frequency of black fur allele (p) is 0.8

As per Hardy Weinberg's  first law of equilibrium

p + q = 1\\

Substituting the value of p in above equation, we get -

q = 1-p\\q = 1-0.8\\q= 0.2

q represents the frequency for white fur allele

Frequency of white fur phenotype is

q^2\\= 0.2^2\\= 0.04

Frequency of homozygous black fur phenotype (BB) is

p^2\\= 0.8^2\\= 0.64

As per Hardy Weinberg's second law of equilibrium -

p^2 + q^2 + 2pq = 1\\0.64 + 0.04 + 2pq = 1\\2pq = 1 - 0.68\\2pq = 0.32\\

Combined frequency of homozygous and heterozygous black fur phenotype is

0.64 + 0.32\\= 0.96
