Question

Which of the following statements can be related to sexual reproduction?

• A. Gametes are usually haploid.
• B. Gametes are usually diploid.
• C. The zygote is usually haploid.
• D. The chromosome number is reduced during mitosis.

Answer 1

The correct option is A Gametes are usually haploid.

Sexual reproduction in higher organisms is characterized by the formation of haploid gametes and their fertilization. The haploid gametes are produced by meiosis which has a half number of chromosomes as compared to the parent cell. It is also known as the reductional division. The haploid gametes obtained from both the parent fuse to form a diploid zygote. Mitosis is an equational division so it will not lead to the reduction in the chromosome.

So, the correct answer is option A.
