Individuals with a sex-linked condition called red-green color blindness do not see the colors red and greed, Red-green color blindness is caused by the recessive allele
b and is carried on the X chromosomes. The dominant allele for normal color vision
is B. When the X chromosome contains the dominant allele, the allele is written as
XB, when the X chromes contains the recessive allele, the allele is written as Xb.
A man who is color-blind marries a woman who is not color-blind and is not a carrier
of the allele for color blindness. Create a Punnett Square to predict the possible
