Question

explain why generally the male child suffers from colour blindness not the female?

Answer 1

here's ur answer... the male child suffers from colour blindness.... because the genes that lead to red–green colour blindness are on the X chromosome (sex-linked).Males have only one X chromosome and females have two. In females, a functional gene on only one of the two X chromosomes is sufficient to produce normal colour vision

Answer 2

sex linked inheritance is the transmission of characters and their determining genes alongwith sex determining genes present on sex chromosomes, which are inherited together from one generation to the next. sex linked traits are more apparent in males than in females. Females generally function as carrier of sex linked disorders because recessive genes can express themselves in females only in the homozygous state.
For example: color blindness, haemophilia etc.
