Problem:
In mice, the dominant allele, G of the X-linked gene Greasy produces shiny fur, while the recessive wild type allele G+ determines normal fur. The dominant allele B of the X-linked Broadhead gene causes skeletal abnormalities including broad heads and snouts, while the recessive whild type B+ allele yields normal skeletons. Female mice heterozygous for the two alleles of both genes were mated with wild type males. Among 100 male progeny of this cross, 49 had shiny fur, 48 had skeletal abnormalities, 2 had shiny fur and skeletal abnormalities, and 1 was wild type.
Required:
Question 1: Diagram the cross described and calculate the distance between the two genes. 0.5 pts
Question 2: What would have been the results if you had counted 100 female progeny of the cross? 0.5 pts
Show your calculations, but you do not need to write out any explanation.
