Question

In male heterogametic type of sex determination

• A. Males do not produce gametes.
• B. Males parent produces similar gametes.
• C. Females parent produces dissimilar gametes.
• D. Males parent produces dissimilar gametes.

Answer 1

The Correct Option is D

In species with male heterogametic sex determination, the male produces two different types of gametes: one containing an X chromosome and the other containing a Y chromosome. This is in contrast to the female, who produces only one type of gamete (X chromosome) in species where males are heterogametic.

This difference in the type of gametes produced by males is why they are referred to as producing dissimilar gametes.

The correct answer is (D) : Males parent produces dissimilar gametes..

Answer 2

In male heterogametic type of sex determination,

The correct answer is: (D) Males parent produces dissimilar gametes.

In male heterogametic sex determination, the male produces two types of gametes with respect to sex chromosomes: one containing the X chromosome and the other containing the Y chromosome. This is different from female heterogametic organisms, where the female produces two types of eggs, typically both with the same sex chromosome.

In species with male heterogametic sex determination, males are XY, and females are XX. This means that it is the male parent who determines the sex of the offspring by contributing either an X or a Y chromosome to the offspring, resulting in either female (XX) or male (XY) offspring, depending on the sex chromosome carried by the male's gamete.

Therefore, the correct explanation is that the male parent produces dissimilar gametes, one carrying the X chromosome and the other carrying the Y chromosome.
