So now that we know what sex chromosomes are, let's take a look at the following example that deals with genetics and the Punnett square. So suppose a colorblind male. So a hemisitis recessive male has a child with a heterozygous normal female. Now, in part A, what is the probability that the child is colorblind? In part, what is the probability that the child is male and colorblind? In Part C, if the child is female, what is the probability that she is normal?
