Question

Individuals who have homomorphic sex - chromosomes produce

• A. two types of gametes
• B. no gametes
• C. one type of gamete
• D. only one gamete in a complete life span

Answer 1

The correct option is C one type of gamete

Homomorphic word comes from the ancient Greek word ‘homos’ meaning “same” and ‘morphe’ means ‘form’. Hence, individuals having homomorphic sex - chromosomes produce one type of gamete. For example, human females produce gametes with 22+X chromosomes only.
Individuals having heteromorphic sex - chromosomes can produce two types of gametes. For example, human males can produce gametes having 22+X or 22+Y chromosomes.
