Question

Genetics problem!
(Sex-linked inheritance)

Answer 1

hello :-)

Answer 2

Make me understand this :(

Cross between colour blind male(XY) Vs Normal(carrier) female(XX)

Answer 3

I have just started this I don't understand :I

Answer 4

let (b)= color blindless, since color blindness is an X-linked recessive disorder so it's a recessive trait.
let (B) = the dominant allele for normal vision, capital letter symbolizes dominant traits

A man who is colorblind can be represented as (Xb Y) as u know, a man's chromosome is XY and a female's chromosome is XX A female with normal vision can be represented as (XB XB) don't forget, she's a normal carrier so here's your cross for the punnet square: (Xb Y) x (XB XB)

Answer 5

As you're reading what Zale101 says, just remember-

Only the X chromosome can carry another allele. Like ( B ) or ( b ).

The Y chromosome doesn't carry an allele.
It's just by itself.
