|
What process occurs in BOTH mitosis and meiosis
|
|
crossovers in prophase I
|
|
|
separation of sister chromatids
|
|
|
anaphase II
|
|
|
division of two genetically identical nuclei
|
Explanation:
Detailed explanation-1: -Anaphase – The spindle fibres begin to contract. This starts to pull the sister chromatids apart. At the end of anaphase, a complete set of daughter chromosomes is found on each pole.
Detailed explanation-2: -Meiosis II is the second division of meiosis. It occurs in both of the newly formed daughter cells simultaneously. Meiosis II is similar to Mitosis in that the sister chromatids are separated.
Detailed explanation-3: -Prophase in mitosis and prophase I of meiosis both start out with double this genetic material-that is, each of the 46 chromosomes has two sister chromatids. The homologous pairs of chromosomes find and line up next to each other, and then something amazing happens: recombination.
