NEET BIOLOGY

Detailed explanation-1: -Males have only 1 X chromosome, from their mother. If that X chromosome has the gene for red-green color blindness (instead of a normal X chromosome), they will have red-green color blindness.

Detailed explanation-2: -X-linked recessive inheritance refers to genetic conditions associated with mutations in genes on the X chromosome. A male carrying such a mutation will be affected, because he carries only one X chromosome.

Detailed explanation-3: -Most commonly, color blindness is inherited as a recessive trait on the X chromosome. This is known in genetics as X-linked recessive inheritance. As a result, the condition tends to affect males more often than females (8% male, 0.5% female).

Detailed explanation-4: -Women can be carriers of the color blind gene and pass the mutation down the family line. If only the father is color blind, there is a 100% chance that his daughters will carry the gene, but they will not be color blind themselves. His sons will neither carry the gene nor be color blind.
