In birds, chromosomal composition of the egg determines the sex. This is called genetic sex determination, with females being heterogametic. But being heterogametic is alone not responsible for sex determination. Other factors like specific genes or autosomal, sex chromosome ratio, etc., are responsible.

Direction: In the following questions a statement of assertion (A) is...
Assertion and Reason Analysis:
Assertion (A): In birds, the chromosome composition of the egg determines the sex.
Reason (R): Female birds are heterogametic.
Explanation:
- Assertion (A) is true: In birds, the sex of the offspring is determined by the chromosomes present in the egg. In birds, the females are the heterogametic sex, meaning they have two different sex chromosomes (ZW), while males are homogametic with two of the same sex chromosomes (ZZ).
- Reason (R) is true: Female birds being heterogametic means that they can produce two different types of eggs - one with a Z chromosome (which will develop into a male chick) and one with a W chromosome (which will develop into a female chick). This chromosome composition of the egg determines the sex of the offspring.
- Reason (R) is not the correct explanation of Assertion (A): While the reason provided is true, it does not directly explain why the chromosome composition of the egg determines the sex in birds. The correct explanation would involve understanding the genetic mechanisms and interactions that lead to this phenomenon.
Therefore, the correct choice is option B, where both the assertion and reason are true, but the reason is not the correct explanation of the assertion.
