The flippleflopper variety of wombats has 42 chromosomes in its body (somatic) cells.

Wombats are cute and cuddly, but this one just left a woman in hospital

How many chromosomes do you expect to see after meiosis (without any errors) in the resulting reproductive cells?

During meiosis, the number of chromosomes in the resulting reproductive cells is halved. This means that in the flippleflopper variety of wombats, the reproductive cells would have 21 chromosomes each, assuming there are no errors during meiosis.
