At which stage would you find a haploid chromosome number?

Question

for grade 9 science

Answer 1

In humans, the only time we have haploid cells is when we form gametes. You know, egg or sperm cells. Once they join we are back to diploid cells. However, there are some species, such as bees, where the male cells are always haploid and the females are diploid.

Answer 2

If you are studying meiosis, the process starts with a diploid cell. By the end of meiosis I the cells are haploid because meiosis I gets the homologous chromosomes apart from each other.
