Question

In which of the following situations does a female person express color blindness?
A. A dominant allele is located on each of the two X chromosomes
B. A recessive allele is located on each of the two X chromosomes
C. A dominant allele is located on X chromosome, and a recessive allele is located on another X chromosome
D. A recessive allele is located on X chromosome, and another recessive allele is located on Y chromosome

Answer 1

females have 2 X chromosomes, while males have only 1 since they r XY

Answer 2

females having 2 X chromosomes give them an advantage because if 1 has the disease, the other one can act as a dominant control and the female is a carrier. The males unfortunatly have only 1 X, so if the X chromosome on male has the disease, ur in a bad situation and will get the disease

Answer 3

it is very hard for females to achieve diseases or linked genes such as color blindness since they have 2 X chromosomes, but it does happen(very rare) and that would be when she has the dominant gene on both X chromosomes
