Gene K controls fur color and it has three alleles: B, s, and y. The pedigree
shows the genotypes of the individuals in the K gene and the haplotypes
for the four molecular markers in the region of the gene.
a) what is the relationship between the three alleles? Use the pedigree to
support your answer and refer to individuals by their positioning in the
pedigree
b) based on the pedigree and the haplotype at the four markers, where is
gene K located? Support your answer.
c)
A genetic map of the 4 markers studied is shown below:
