Answer:
50% will be normal and 50% will be carriers
Explanation:
Color blindness is a reduced ability to distinguish between certain colours.
The condition is often inherited. Other causes include certain eye diseases and medication. More men than women are affected.
If such a carrier woman with normal vision (heterozygous for colour blindness) marries a normal man (XY), the following progeny may be expected in the generation: among the daughters, 50% is normal and 50% are carriers for the diseases; among sons, 50% are colour blind and 50% are with normal vision.
<span>Homologous chromosomes exchange DNA during meiosis in a process called crossing-over. Crossing-over sometimes involves an unequal swapping of DNA. Basically one chromosome in the pair gets extra DNA.</span>
