Question

Does meiosis never occur in organisms that are haploid?

Answer 1

yes in haplontic lifecycle meiosis occurs.when the zygote of haploid organism is formed (2n)
then further development of the zygote takes place to form embryo by miotic division which will be haploid

Answer 2

Meiosis do occur in haploid organisms also.

Explanation:

Haploid is a condition in which cells contain one set (N) of chromosomes.

Diploid is a condition in which cells contain two pairs (2N) of chromosomes.

Usually, meiosis occurs in diploid organisms, where the 2N chromosomes undergo meiosis and become four different N chromosomes.

But, in rare situations, meiosis takes place in haploid organisms also, where two haploid cells first fuse together to become diploid zygote and then undergo meiosis.
