Question

A woman having the genotype $X^{c}X$ where $X^c$ is the allele for colour blindness would be affected.

• A. True
• B. False

Answer 1

The correct option is B

False

The woman is a carrier for the disease as she has only one defective copy of the gene (allele) on one of her X- chromosomes. This is an X linked recessive disease and only homozygous females are affected.
