Answer:
Correct Answer: A
Solution:
Sex linked traits are governed by recessive genes.
They produce disorders in males more often than in females.
They express themselves in males even when represented by a single allele because y-chromosome does not carry any corresponding alleles.
They appear in females only when the father possess the trait and the mother is a carrier.
