How many chromatids do tetrads have
WebFrom what I understand there are 4 chromatids in a tetrad and in the spermatogonium/ oogonium there are 4 chromatids present. However, looking at the primary spermatocyte there are 2 sets of tetrads present which would mean there are 8 chromatids. WebHumans usually have 22 pairs of homolog chromosomes (autosomes) and as sex chromosomes 2 x chromosomes (in female), or 1 x and 1 y chromosome (in males), thus in total 46 chromosomes per body cell (see human karyogram; 2n = 46) and 92 chromatids per cell after replication. last modified: 31 Jul 2014
