Question

If there are four chromosomes present during prophase-1, how many chromosome are therein each cell at the end of anaphase-2

Answer 1

Similarly, in humans (2n=46), there are 46 chromosomes present during metaphase, but 92 chromatids. It is only when sister chromatids separate – a step signaling that anaphase has begun – that each chromatid is considered a separate, individual chromosome.
