Question

Why must males inherit colorblindness or hemophilia from their mothers?

Answer 1

Males inherit colorblindness or hemophilia from their mothers because these conditions are caused by genes located on the X chromosome. These conditions are more commonly passed down from carrier mothers to their sons.

Step-by-step explanation:

Males inherit colorblindness or hemophilia from their mothers because these conditions are caused by genes located on the X chromosome. Colorblindness and hemophilia are examples of X-linked recessive inheritance, which means that they are more commonly passed down from carrier mothers to their sons. Although females can also inherit and carry these genes, they usually do not display symptoms because they have two X chromosomes and one functional copy of the gene can compensate for the recessive mutation. On the other hand, males only have one X chromosome, so if they inherit a mutated gene from their mother, they are more likely to develop the condition.

Answer 2

Men must inherit colorblindness or hemophilia from their mothers because colorblindness and hemophilia are located on the X chromosome, which are inherited from their mother.
