Question

Figure 18-22 shows 10 haplotypes from a population before a selective sweep and another 10 haplotypes many
generations later after a selective sweep has occurred for
this chromosomal region. There are 11 loci defining each
haplotype, including one with a red allele that was the
target of selection. In the figure, two loci are designated
as A and B. These loci each have two alleles: one black
and the other gray. Calculate the linkage disequilibriumparameter (D) between A and B, both before and after
the selective sweep. What effect has the selective sweep
had on the level of linkage disequilibrium?

@ 2 W S Rehpogs are mythical creatures. They are small and not very smart. Rehpogs live on the ground in a flat, warm habitat. Their fur texture and color ranges from thick purple fur to thin pink fur, depending on allele distribution. The dominant fur allele (R) codes for thick purple fur. The recessive allele (r) codes for thin pink fur. REMEMBER: a phenotype (fur color) is the physical expression of a genotype (two- letter code for the alleles present in that individual). Each individual has two alleles for fur color: X RR genotype is homozygous dominant = Thick purple fur phenotype Rr genotype is heterozygous = Thick purple fur (because of the presence of one dominant allele) rr genotype is homozygous recessive = Thin pink fur (because of the absence of a dominant allele) For the purposes of this experiment, Rehpogs mate once per year and produce two offspring each year. Rehpogs are monogamous, faithful and fertile. # 3 e d C C $ 4 r f V % 5 t g Oll 6 b y h & 7 O 8 n JL u i j O L m…
