Sex-Linked Punnet Square: Colorblindness and Normal Vision?

The Gene for normal vision (C) and the recessive (c) for colorblindness ride on the X chromosome (they are sex-linked). Cross a homozygous normal visioned female with a colorblind make.





I don't even know how to start.





Would the offspring be something like XXCc..I am so confused lol.

colorblind male XcY





XC XC





Xc XCXc XCXc





Y XCY XCY





offspring:


100% of males would be normal


100% of females would be normal but would carry the trait
