Answer:
The probability of the parents having yellow-bellied off-spring is 100% because all the genotypes have a dominant Y.

A Punnett square for the woman shows she is a carrier for colroblindness and her genotype is XcX
The chance of having a son is 50% and the chance of that son having colroblinness is 50%
