Question

If you are a colour-blind male (Xc Y) and you have children with a carrier female (Xc X), what percentage of your children could be colourblind OR carriers? ***c means that chromosome has the colourblind gene***

Answer 1

Answer:

0.50% are colour blind  and 0.25% are carrier.

Explanation:

Colour blindness is a common hereditary condition which is usually passed down from parents to offspring This is a X linked disorder

Given:

male   -  Xc Y (  color blind)

Female- Xc X ( carrier)

gametes, Xc, Y        *  Xc , X

F1  generation:  

Xc Xc,  Xc X,   Xc Y,   XY

So Xc Xc female and Xc Y male are colour blind because this disease is X- linked recessive disease,

and Xc X female is carrier,

XY male is normal.
