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.

Which Hardy-Weinberg equation relates the frequencies of the genotypes for a particular gene locus?

Two SNPs are located in the short arm of chromosome 12. SNP1 has allele frequencies of 60% T and 40% C, and SNP2 has allele frequencies of 40% A and 60% G. What is the frequency of the haplotype T-G in a population if the two SNPs are in absolute linkage disequilibrium and if they are in linkage equilibrium?

What is the first variable that can be calculated given these data, and what is the final variable we are requesting you to calculate? "In Finland, 256 people out of 10,000 are homozygous for the CCR5 allele mutation resulting in HIV resistance. Assuming the locus is in Hardy-Weinberg equilibrium, what is the expected genotype frequency of heterozygous carriers for the CCR5 mutation?"
