Question

If a polygenic trait is controlled by two gene pairs than what will be the probability of individuals in F2 generation showing exact resemblance to F1 generation :-

Answer 1

Answer:

If a polygenic trait is controlled by two gene pair then the probability of individuals in F2 generations showing exact resemblance to F1 generation will be 6/16.

Answer 2

Answer:

Genes are responsible for carrying forward the traits from the parents to the offspring. In this question, the transfer of trait completely depends on the location of the genes on the chromosome.

Since the genes on the chromosome are places closed, the probability of similarly will be more than the ones which are located at a larger distance. In the latter case, the probability of linkage would be less.
