Give reason -

Colour blindness

occur more in male child than

in female child.​

Answer 1

Answer:

It occurs in about eight per cent of males and only about 0.4 per cent of females. This is because the genes that lead to red–green colour vision deficiency blindness (OPN1LW and OPN1MWI) are on the X chromosome (they are 'sex-linked'). Males have only one X chromosome and females have two.
