QUESTION
The inheritance that is passed through the X chromosome is known as?
OPTIONS
(A) Sex-linked
(B) Sex-linked
(C) Sex influenced
(D) Extra chromosomal
ANSWER
(A) Sex-linked
EXPLANATION
Inheritance through a gene located on the X chromosome is called X-linked or sex-linked inheritance. The duplicate option has the same term and is therefore not a distinct alternative, whereas sex-influenced traits depend on sex-specific expression and extra-chromosomal inheritance involves genetic material outside the nuclear chromosomes.
