What is surprising about the observed number of two-locus genotypes. Introduction: In two-locus genotype, four different types of alleles are included to form differentgenotypes. In this problem, there are two alleles A 1 and A 2 , which are located at one locus and B 1 and B 2 are located on the second locus.

To describe: What is surprising about the observed number of two-locus genotypes.

Introduction: In two-locus genotype, four different types of alleles are included to form differentgenotypes. In this problem, there are two alleles A₁ and A₂, which are located at one locus and B₁ and B₂ are located on the second locus.

b.

Summary Introduction

To explain: Whether each locus is at Hardy-Weinberg equilibrium or not.

Introduction: If the value of the Hardy-Weinberg equation is equal to one, it means that the locus is atHardy-Weinberg equilibrium. If the value exceeds 1, it shows that there is an excess of homozygous genotypes. On the other hand, if the value of the Hardy-Weinberg equation is less than 1, it says that there is an excess of heterozygous genotypes.

c.

Summary Introduction

To explain: Whether the two loci are close to one another, or far apart in the genome.

Introduction: Loci are just sites on the chromosome from which some portion of gene interchange with the segment of another chromosome during crossing over and recombination.
