Summary Introduction

a.

To determine:

The reason for Eq. 22.7 being true for the extreme case where phenotypic variations are caused because of genes.

Introduction:

In some cases in a single pregnancy, two children are born. These children born in a single pregnancy are called twins. They can be monozygotic or dizygotic.

Summary Introduction

b.

To determine:

The reason for Eq. 22.7 being true for the extreme case where no phenotypic variations are caused because of genes.

Introduction:

Twins are those children that are born in the same pregnancy. If a single zygote splits into two to form two different embryos, then it is a case of monozygotic twins (MZ). On the other hand, if the embryos are formed by two fertilizations taking place in the same uterus, then the twins born are known as the dizygotic twins (DZ).

d) Please refer to the table. If only data on the variances for F1, F2 and BC1 populations were available, how will the broad sense heritability estimate change? Show solutions.

A characteristic has a narrow-sense heritability of 0.6. a. If the dominance variance (VD) increases and all other variance components remain the same, what will happen to narrow-sense heritability? Will it increase, decrease, or remain the same? Explain. b. What will happen to broad-sense heritability? Explain. c. If the environmental variance (VE) increases and all other variance components remain the same, what will happen to narrow-sense heritability? Explain.

One variety of pigs reach maturity at 81 days with a variance of 6.4 days2 while a second variety takes 93 days to reach maturity with a variance of 6.6 days. An F2 population derived from these populations takes 87 days to reach maturity and has a variance of 8.5 days. What is the broad-sense heritability for this trait?
