Biology for IGCSE & O level - Inheritance (Section 11 - No. 10)
What type of inheritance is most likely to affect males more often than females?
Autosomal dominant
Autosomal recessive
X-linked dominant
X-linked recessive
Explication
X-linked recessive traits are more common in males because they only have one X chromosome; therefore, only one copy of the recessive allele is needed for expression.
