![]() ![]() When the chromatids are separated they are now called chromosomes ![]() Anaphase II splits the sister chromatids which now separate (23 chromatids go to one pole and 23 chromatids go to other pole). The parent cell starts with 23 chromosomes (EACH double stranded=two sister chromatids, so there are 46 chromatids. This means that in meoisis II when we split the sister chromatids: It is only when the sister chromatids separate are they each considered separate chromosomes. ![]() The single strand chromosome (1 chromosome) became two stranded yet attached identical sister chromatids (still 1 chromosome) Likewise chromosome 5 of dad is similar to chromosome 5 of mom)Īfter replication how many chromosomes do we have? In interphase before S (replication phase) we have 46 single stranded chromosomes: 23 are from mom and 23 are from dad (they code for the same things meaning chromosome 1 of mom codes for the same thing as chromosome 1 of dad. Remember that when replicating in interphase, the chromosome number DOES NOT CHANGE ![]()
