Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which meiotic division more closely resembles mitosis?
A
Meiosis I
B
Meiosis II
C
Both resemble mitosis closely.
D
Both have significant differences from mitosis.A replicated chromosome and a bivalent.
Explanation: 

Detailed explanation-1: -Meiosis I is followed by meiosis II, which resembles mitosis in that the sister chromatids separate and segregate to different daughter cells.

Detailed explanation-2: -Meiosis I is a type of cell division unique to germ cells, while meiosis II is similar to mitosis.

Detailed explanation-3: -The second division of meiosis (the equational division) resembles mitosis: Sister chromatids separate and segregate.

Detailed explanation-4: -Some single celled eukaryotes such as yeast also use meiosis. Meiosis begins similarly to mitosis (a cell has replicated its chromosomes and grown large enough to divide), but requires two rounds of division. In the first, known as meiosis I, the homologous chromosomes separate and segregate.

Detailed explanation-5: -Meiosis II resembles a mitotic division, except that the chromosome number has been reduced by half. Thus, the products of meiosis II are four haploid cells that contain a single copy of each chromosome. In mammals, the number of viable gametes obtained from meiosis differs between males and females.
