Question

Which of the following is true for an animal, with a diploid number of chromosomes equal to 30?

• A. Not be able to undergo meiosis because gametes would end up with an odd number of chromosomes
• B. Produce two gametes with 30 chromosomes each during meiosis
• C. Produce four gametes with 30 chromosomes each during meiosis
• D. Produce two gametes with 15 chromosomes each during meiosis
• E. Produce four gametes with 15 chromosomes each during meiosis

Answer 1

Answer: (E)

Produce four gametes with 15 chromosomes each during meiosis

In meiosis, a diploid cell gives rise to four haploid cells i.e. each cell has half the number of chromosomes as compared to the parent cell so it is called reductional division. so an animal with a diploid number of chromosomes equal to 30 will produce four gametes. Each gamete will contain 15 chromosomes due to meiosis. Thus option D is the correct answer.
