What happened is the first division: each homologous chromosome have separated becoming 23. Now once in the second division: each chromatid of the same chromosome are going to get separated. read more
*Prophase I : 46 Chrms, & each chromosome has 2 chromatid. *Prophase II: 23 Chrms, each one has 2 chromatids. *Telophase II: 23 chrms, each one has 1 chromatids. read more
In the synthesis phasethe cell 46 chromosomes or 23 homologous chromosome pairs are replicated to double the amount which will de given to 2 daughter cells of same genetic composition. Prophase is the phase where the chromatin is condensed to form chromosomes, nuclear membrain disappeared and the centrioles are moved to the two poles of the cell. read more
For humans, this means that during prophase and metaphase of mitosis, a human will have 46 chromosomes, but 92 chromatids (again, remember that there are 92 chromatids because the original 46 chromosomes were duplicated during S phase of interphase). read more
