Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In Meiosis if the parent cells has 40 chromosomes, then how many will the daughter cells have
A
40
B
10
C
20
D
18
Explanation: 

Detailed explanation-1: -If the number of chromosomes in the daughter cells is 40, then the number of chromosomes in the parent cell will be 80.

Detailed explanation-2: -Each daughter cell will have 30 chromosomes.

Detailed explanation-3: -Thus, if a diploid cell contains 40 chromosomes, then the haploid cell will contain 20 chromosomes. During meiosis, a diploid cell undergoes two successive rounds of cell division to form four haploid cells.

Detailed explanation-4: -Complete answer: When an organism with 20 chromosomes undergoes meiotic division it produces four gametes each having half the number of chromosomes(10) the parent cell has.

Detailed explanation-5: -Telophase II: During telophase II, cell division begins again in each of the two daughter cells, creating 4 daughter cells. Each of these 4 daughter cells contains 23 chromosomes, making them haploid, and none of the 4 is exactly alike (due to crossing over and independent assortment).
