Question

Red-green color blindness is caused by an X-linked recessive gene. In a family, the mother is a carrier of this gene while the father does not have the gene. What are the possible effects on their children?

Answer 1

Draw a punnett square
mother is carrier so she is homozygous: XXc or XcX
c=colorblind
father is normal so XY

50% of boys will be colorblind
50% of girls will be carrier
