In metaphase, there are 46 homologous pair of chromsomes a total of 92 sister chromatids. then in Anaphase, sister chromatids split up from the 46 homologous pair having 46 sister chromatids or (46 chromsomes since each chromatid is conmsidered a chromosome) then there are two cells of 46 chromatids or 46 chromosomes. Is this why there are 2 diploid cells at the end? 2 diploid cells meaning 46 chromatids or 46 chromosomes in each cell?

please tell me if this is correct.
in metaphase 1: there are 46 homologous chrmosomes(is this right? or 23 homologous chromosomes) then there are 23 homologous chromosomes= 46 chromatides at each pole in Anaphase 1. In Telophase 1 and Cytokinesis, there are 23 homologous pair of chromosomes or chromatids in each cell(2 cells). Then prophase II, there are two 23 homologous pair of chromosome in two cells to start out with (46 chromatids). then Metaphase II, the 23 homologous pair of chromosome separate chromatids to each pole, each pole having 23 chromatids. so this happens twice because of two cells. Now Telophase II, Cytokinesis there are 23 chromatids in each cell (4 cells) I assume that now since chromatids are separated they are now called chromosomes is this right? As a result we have 4 haploid cells. Do we have 4 haploid cells because in each cell there are 23 chromatids or 23 chromosomes?

This question has no racist insinuation or anything, I am simply wondering how the different races were created: does one human race derive from another? Does each race derive from a different race of ape? Do the different races derive from random mutations that created them, from a specific but common ancestor? Also what is the case in cats and dogs for example, who have so many different races?

Do we have odors even when we're clean?. I've never smelled a weird odor in anyone "clean" before. But I heard some people say that some black people say we "white people" smell. and some white people say that black people smell-- I don't mean to be racist, So please don't get mad at me :). All I'm trying to say is, do human beings smell, but it takes someone from another race to actually smell it?

I have a debate topic in biology. I was put on the con side of evolution, which makes it the same as creationism. It's pretty hard, because you have all this evidence on evolution. Are there any strong statements supporting con-evolution? If so, what are they?
