Chapter 4, Problem 3PDT

a.

Summary Introduction

To calculate: The allele frequencies for each population and determine whether the population is currently at Hardy-Weinberg equilibrium.

Introduction: The allele that is located at a particular locus in a population, its relative frequency value is calculated as a fraction, this frequency is known as allele frequency.

b.

Summary Introduction

To explain: Whether there is an excess of homozygous or heterozygous genotypes, for the populations which are not at Hardy-Weinberg equilibrium.

Introduction: Homozygous genotypes are those genotypes which carry the same type of alleles. If both the alleles are recessive, the genotype is said to be homozygous recessive otherwise if it is dominant, the genotype is called as homozygous dominant. On the other side, heterozygous genotypes carry different alleles.

c.

Summary Introduction

To explain: The number of generations of random mating to reach the population at the equilibrium, for the populations which are not at Hardy-Weinberg equilibrium.

Introduction: If any population is not at Hardy-Weinberg equilibrium, it shows that one of the laws of Hardy-Weinberg has been violated. Deviation from the Hardy-Weinberg equilibrium, correspond to other factors of evolution.

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.
