In garden peas, tall (T) vine is dominant over short (t) vine, and round pea pod (R) is dominant over wrinkled pea pod (r). Cro

Aleksandr [31]

Answer:

Explanation:

Given:

Traits

T (tall, dominant) and t (short)

R (round, dominant) and r (wrinkle)

Crossing parents

hetero-zygous. tall wrinkled (Ttrr)

phenotype tall is given hetero-zygous., so Tt

phenotype wrinkled is recessive, so must be homo-zygous rr

Foiled genotypes (Tr, tr, each with 50%)

short hetero-zygous. round (ttRr)

phenotype short is recessive, so homo-zygous rr

phenotype round is given heteroz. so Rr

Foiled genotypes (tR, tr, each with 50%)

Answer:

The correct option is B) as the light colored moths were seen and eaten, the allele for dark colour became more prevalent in the population.

Explanation:

The process of natural selection tends to favour those organisms which are better adapted to live in an environment. Evolution changes the allele frequencies of a population over time depending on the traits favoured by natural selection.

Before the industrial revolution, the colour of the trees was lighter and hence, the light coloured moths were better adapted to such environments as they could hide from predation. After the industrial revolution, the colour of the woods of trees became darker. The light coloured moths were no more able to hide from their predators and hence their population declined.
