Question

A farmer wishes to increase chicken egg laying from a mean of 4 eggs per week. The narrow sense heritability for egg laying is 0.1. If the farmer selects parents with an average egg laying rate of 5 eggs per week, what is the expected average egg laying rate in the offspring?

Answer 1

Heritability is a statistic used in breeding and genetics works that estimates how much variation in a phenotypic trait in a population is due to genetic variation among individuals in that population

⧫ Solution ⧫. The selection differential is 5 − 7 = 2 mm, and the selection response is Therefore, theheritability in the narrow sense is:

The additive genetic portion of the phenotypic variance is known as Narrow-sense heritability and is defined as

h²      =      0.1²

         Var(A)      =     ?

                        Var(p)      =     (5-7)    =2

                0.02     is the average egg laying in the offsprings.
