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: Marker 1 Marker 2 Marker 3 Marker 4 JU 5 cM 6 cM 12 cM What is the probability that an offspring of a cross between l-1 and I-2 would have the haplotype below?
