Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Are the cells produced in meiosis identical or unique?
A
Identical
B
Unique
C
It’s random
Explanation: 

Detailed explanation-1: -Mitosis creates two identical daughter cells that each contain the same number of chromosomes as their parent cell. In contrast, meiosis gives rise to four unique daughter cells, each of which has half the number of chromosomes as the parent cell.

Detailed explanation-2: -The gametes produced in meiosis are all haploid, but they’re not genetically identical.

Detailed explanation-3: -Mitosis produces two diploid (2n) somatic cells that are genetically identical to each other and the original parent cell, whereas meiosis produces four haploid (n) gametes that are genetically unique from each other and the original parent (germ) cell.

Detailed explanation-4: -Unlike in mitosis, the daughter cells produced during meiosis are genetically diverse. Homologous chromosomes exchange bits of DNA to create genetically unique, hybrid chromosomes destined for each daughter cell.

Detailed explanation-5: -Genetic variation is increased by meiosis Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA. This produces a unique combination of genes in the resulting zygote.
