a. To determine: The traits that have the greatest and the lowest heritability. Introduction: Phenotypic traits are passed on from one generation to the next through genes. Events such as crossing over and mutations are responsible for bringing change in the genes and thus change in the phenotypic characters.

Summary Introduction

a.

To determine:

The traits that have the greatest and the lowest heritability.

Introduction:

Phenotypic traits are passed on from one generation to the next through genes. Events such as crossing over and mutations are responsible for bringing change in the genes and thus change in the phenotypic characters.

Summary Introduction

b.

To determine:

The relative matching of the given statistics with the estimation of relative heritabilities done in part (a).

Introduction:

The genes present in an organism determines the phenotypic traits of an individual. Along with the genetic factors, environmental factors also play a role to some extent in determining the physical characteristics of an individual.

Students have asked these similar questions

You aim to test the hypothesis that the Tbx4 and Tbx5 genes inhibit each other's expression during limb development. With access to chicken embryos and viruses capable of overexpressing Tbx4 and Tbx5, describe an experiment to investigate whether these genes suppress each other's expression in the limb buds. What results would you expect if they do repress each other? What results would you expect if they do not repress each other?

You decide to delete Fgf4 and Fgf8 specifically in the limb bud. Explain why you would not knock out these genes in the entire embryo instead.

You implant an FGF10-coated bead into the anterior flank of a chicken embryo, directly below the level of the wing bud. What is the phenotype of the resulting ectopic limb? Briefly describe the expected expression domains of 1) Shh, 2) Tbx4, and 3) Tbx5 in the resulting ectopic limb bud.
