Answer to Question #138946 in Genetics for Vanessa

Question

A woman is heterozygous for three linked autosomal genes and has the genotype GgHhMm. The three genes are arranged on the chromosomes in the order listed (i.e. G then H then M). Her husband is homozygous recessive for each of the genes. They have eight children with the following genotypes:
Three are GghhMm.
Two are ggHhmm.
One is GgHhmm.
One is Gghhmm.
One is gghhmm.
What is the most likely combination of alleles on each of the mother’s chromosomes? Explain.
List the genotypes of the recombinant children above. For each of these children, determine the location of the required crossover(s) in the mother’s oocyte to create their recombinant chromosome by identifying the two genes between which the crossover(s) occurred.
List the other possible recombinant genotypes that have not appeared in the offspring.
