Three models of cellular reproduction are shown below.

Meiosis Binary Fission Mitosis



Which explanation about cellular reproduction is best supported by the models?

Mitosis and melosis both produce diploid and haplold gametes during cellular replication

Binary fission and mitosis both produce daughter cells that are identical to the parent cells.

Melosis and binary fission both include the process of crossing over during cellular replication

Melosis and mitosis both produce daughter cells with fewer chromosomes than the parent cells.

Binary fission and mitosis both produce daughter cells that are identical to the parent cells.

Explanation:

It is a form of asexual reproduction that usually occurs in prokaryotes such as bacteria and some unicellular eukaryotes such as amoeba and paramoecium. In binary fission, the segregation and the duplication of genetic material or DNA replication occur simultaneously. Then cytokinesis occurs where the cell divides into two or more new cells (or organisms) and each one receives a copy of parental DNA.

It is a type of eukaryotic cell division where a diploid parent cell divides to produce two new diploid daughter cells that are genetically identical to itself and have the same number of chromosomes as the parent cell. Mitosis helps in the growth of an organism and replace or repair damaged cells. Sometimes, crossing-over can also occur at mitosis.

It is a form of eukaryotic cell division which helps in sexual reproduction. It is used in the production of gametes such as sperm or egg cells. Here, a diploid parent cell divides to produce four new haploid daughter cells by sharing its genetic material between the and each daughter cell has half the number of chromosomes as that of the parent cell. Here, the crossing over of chromosomes results in the exchange of genetic material between maternal and paternal chromosomes and causes genetic diversity.
