The male human is heterozygous for autosomal gene A and B and also hemizygous for hemophilic gene h then his genotype will be AaBbXhY because hemophilia is a sex linked trait that is present on X- chromosome. So the total number of gametes will be abXh abY, ABXh ABY, AbXh, AbY, aBXb,aBY. So the proportion of abXh sperm will be 1/8.
