Sagot :
an example of an X-Linked recessive disorder is colorblindness.
Answer:
The answer is C: Color blindness
Explanation:
The pattern of inheritance in case of color blindness is X-linked recessive. It means the gene responsible for color blindness is present on X-chromosome. As we know that male has only one copy of X whereas females have two copies of X, so their expressions vary in males and females. In case of X-linked recessive genes, two recessive copies must be present in females for their expression whereas in males a single recessive copy of recessive gene is sufficient to show the expression. If a women is heterozygous for color blindness gene then she will act as a carrier.
