The narrow-sense heritability (h 2 ) for both the trait in the given problem. Introduction: The term heritability refers to the proportion of the genetic variance to the total variance. It is classified into two types namely broad sense heritability and narrow sense heritability. Narrow-sense heritability (h 2 ) is the ratio of additive variance to the total phenotypic variance. It is widely used by the animal and plant breeders for accurate prediction of the population for artificial selection.

(a)

Summary Introduction

To determine:

The narrow-sense heritability (h²) for both the trait in the given problem.

Introduction:

The term heritability refers to the proportion of the genetic variance to the total variance. It is classified into two types namely broad sense heritability and narrow sense heritability. Narrow-sense heritability (h²) is the ratio of additive variance to the total phenotypic variance. It is widely used by the animal and plant breeders for accurate prediction of the population for artificial selection.

(b)

Summary Introduction

To determine:

The trait that will respond likely to selection.

Introduction:

The term selection refers to the process of selecting up specific individuals which contain desired phenotype or trait for the future breeding process. As a result of this selection process, a population which contains more frequency of individual with desired characters can be developed. The narrow sense heritability (h²) is used to find the impact of selection.
