The Y-chromosome is an accurate indicator of a person's external gender organ. I agree with this statement.
What is Gender-determination?
It is the process of determining the gender of a particular organism on the basis of chromosomal numbers or its functions.
As we all know that a human female has a pair of X-chromosomes (homomorphic), while a human male has an X and a Y-chromosome (heteromorphic). Y-chromosome is a gender-determining chromosome in humans. A person having an XY set of chromosomes produces a hormone called testosterone secreted by the testes, while an individual having a XX chromosome produces a hormone called estrogen secreted by the ovary. And the external gender organs are developed as the chromosomes and hormone influences for the same.
Therefore, the Y-chromosome is an accurate indicator of a person's external gender organ.
