can you tell me how would i form a punnet square showing a disease with sex linked traits?
Answer Thanks for using AllExperts, Byrd. The answer to this question requires a visual presentation, so I’m including links at the end that show how Punnet squares are formed for sex-linked traits. First, recall that sex-linked traits are those carried on the sex chromosomes, X and Y in humans. Disease transmission for traits carried on the X differs from those carried on the Y, so let me cover both separately. Normal inheritance problems depend on you being able to tell the difference between dominant and recessive traits; sex-linked inheritance problems add the complication of which sex the offspring will be. First, let’s look at the X chromosome. In this context, a “diseased” chromosome means one that carries the allele for a genetic disease. Men can contribute X or Y chromosomes to their offspring; woman can contribute only X chromosomes. This happens, of course, because men have an XY genotype and women an XX genotype. Thus, any diseases carried on a particular X chromosome will
