Drag each tile to the correct location.

Answer:

Mitosis and meiosis are similar at the level of writing, and possess a very close mechanism; however, they do not achieve the same result!

Mitosis corresponds to a single "asexual" cell division of somatic cells (almost all cells in the body), and clones two daughter cells from a mother cell, which will be identical, and inherit exactly the same heritage genetic, indeed these two daughter cells will each have an identical karyotype (same chromosomes) and an identical genotype (same alleles) to that of the mother cell.

Meiosis corresponds to two successive "sexual" cell divisions affecting only germ cells; starting from a diploid cell (chromosomes present in pairs), meiosis leads to the formation of four gametes (haploid sexual cells, spermatozoa or oocytes) (a single copy of the chromosomes). Then, during fertilization, two gametes (each from meiosis, in the male and female) come together to form a zygote, in which diploidy will be restored.

The right answers are:

create two identical cells ==> mitosis

create four non-identical cells ==> meiosis

create haploid cells ==> meiosis

creates diploid cells ==> mitosis

occurs in all cels other tha gametes ==> mitosis

occurs in all cells related to sexual reproduction ==> meiosis
