Genotypic and Phenotypic Ratios
with Sex-Linked Lethal Genes
"LadyKiller" is a lethal gene located on the Z (sex chromosome) in chickens. The location of this gene is between the locus for silver color and the locus for light down.
Assume a male carrier for the lethal allele (lk) is mated to produce 300 live chicks. What is the expected number of males and females given the presence of this allele?
