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?

Solutions

Expert Solution

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.

A freerange egg farmer has a field of 4,000 m2 area. On this field there are currently 500 chicken. Each chicken lays 150 eggs per year. As space and food is limited on the field, for every tenth chicken added to the field, each chicken lays 1 egg less per year. How many eggs per year can the farmer expect at most?
