Solution :
Colourblindness is X-linked recessive disorder, in which a person is unable to differenciate between red and green colour. It is also known as daltonism, eg, if colourblind man marries a J girl who is normal, 50% of progenies will be normal (boys) and 50% will be carrier (girl). and if a carrier girl marries a colourblind man, 50% of female progenies and 50% of male progenies will be colourblind.You need to login to perform this action.
