CELL DIVISION

MEIOSIS AND GENETIC VARIATION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Happens only in Gametes (sex cells):
A
Mitosis
B
Meiosis
Explanation: 

Detailed explanation-1: -Meiosis only occurs in reproductive cells, as the goal is to create haploid gametes that will be used in fertilization. Meiosis is important to, but not the same as, sexual reproduction. Meiosis is necessary for sexual reproduction to occur, as it results in the formation of gametes (sperm and eggs).

Detailed explanation-2: -Answer and Explanation: Meiosis only occurs in gametes and not in somatic cells. This is because meiosis creates genetically unique haploid cells which is only a feature of sex cells. Somatic cells divide through a process known as mitosis.

Detailed explanation-3: -Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction.

Detailed explanation-4: -Gametes are an organism’s reproductive cells. They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm. Gametes are haploid cells, and each cell carries only one copy of each chromosome.
