How many chromatids are present in Anaphase 1 of meiosis 1 of diploid cell having 20 chromosome?
Dear Student,
During Anaphase I of meiosis I homologs chromosome separate and move to opposite poles. Sister chromatids remain attached at their centromere. The number of chromatids in Meiosis I stage = 2(number of chromosomes).Because there is the formation of tetrad in prophase I which undergoes crossing over and later homologs chromosome separate in anaphase I.Therefore number of chromatids in anaphase I if there are 20 chromosome is equal to 40 chromatids.
Regards.
