Question

Do male and female offspring possess the same likelihood of carrying the colorblindness trait in their genotype

Answer 1

Complete question:

Punnet squares for genes found in sex chromosomes are unique in that the pattern of inheritance of these traits is gender-specific. For example, examine the following Punnet square for color blindness, a trait found in the X chromosome (Y chromosome carry only a few genes but they do not possess enough coded information to initiate the development of the male).

Xcb represents the X chromosome carrying the color blindness trait. The allele for color blindness is recessive to the normal form of the gene (X).

Punnet square:

                                      Mother

                                Xcb             X

Father         X          X Xcb        X X

                  Y          Xcb Y        X Y
