What is a major difference between mitosis and meiosis I in a diploid organism?
a. Sister chromatids separate in mitosis, while homologous pairs of chromosomes separate in meiosis I.
b. Only meiosis I results in daughter cells that contain identical genetic information.
c. DNA replication takes place prior to mitosis, but not before meiosis I.
d. Sister chromatids separate in mitosis, while homologous pairs of chromosomes separate in meiosis II.

In anaphase of meiosis, all the chromosome line in a single track in the metaphase plate. In metaphase I of meiosis I, chromosome line the metaphase plate of the cell in homologous pairs. This is why at the end of telophase in anaphase I, the genetic material of the daughter cells is halved while in mitosis, it remains the same. Meiosis II is usually similar to mitosis.

a. Sister chromatids separate in mitosis, while homologous pairs of chromosomes separate in meiosis I.

Further explanation

In terms of understanding Mitosis and Meiosis are different. For Mitosis is the part of cell division, where the chromosomes in the nucleus split into 2 sets of identical chromosomes, each of which has a nucleus.

then Meiosis is cell division which reduces the number of chromosomes by half. This process occurs in every sexual reproduction.

In mitotic cell division the reproductive type is asexual. While meiosis division is cell division with a type of sexual reproduction.

organisms that experience or pass through the process of cell division of Mitosis ie all types of organisms. For Meiosis which experiences this type of division only organisms or living things such as humans, animals, plants, fungi.

Considering that Mitosis is a process of division with the asexual type of reproduction, genetic mixing does not occur, which is certainly the opposite of Meiosis in which there is a process of genetic mixing.

Still related to the type or type of reproduction. The absence of genetic mixing in Mitosis makes the characteristics of daughter cells and stem cells identical or identical. For Meiosis there is a difference between daughter cells and stem cells given the genetic mix.

Mitosis usually occurs for cell reproduction and for the growth and repair of cells in the body of an organism or living things. Meiosis occurs to distinguish an organism genetically through sexual reproduction.

Mitosis, which is a process of asexual division, makes the number of chromosomes produced unchanged or constant. For Meiosis which is sexual division, the number of chromosomes changes to half of the initial chromosome cells.
