Biologists think that endosymbiosis gave rise to mitochondria before plastids partly because: (All eukaryotes have mitochondria whereas many eukaryotes do not have plastids)
For meiosis, this is in anaphase I. For the separation of sister CHROMATIDS in mitosis, this is anaphase. Either way, the separation of two whole chromosomes or two chromatids within one whole chromosome takes place during anaphase. This occurs after metaphase and before telophase and cytokinesis.

<span>A tiger looks so much different as an adult than it did as a single fertilized egg because it developed through different stages from being a zygote (fertilized egg), to becoming an embryo (where it experiences intense cellular changes), to becoming a fetus (where it gains a great measure of cell specialization, and develops distinct tissues and organ systems). After birth, the tiger still undergoes further growth and development into adulthood. This is largely regulated by the expression of different genes at different times and also by environmental factors.</span>
