Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A lion contains 80 chromosomes. The number of chromosomes a lion egg cell, produced by meiosis, will be?
A
40
B
80
C
20
D
60
Explanation: 

Detailed explanation-1: -Answer and Explanation: If a cell with 80 chromosomes undergoes mitosis, the daughter cell will also have 80 chromosomes. The daughter cells will be genetically identical to one another. In contrast, a cell with 80 chromosomes would have 160 chromatids prior to mitosis.

Detailed explanation-2: -The haploid cells contain half the number of chromosomes as the diploid cells. 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-3: -10 chromosomes Was this answer helpful?

Detailed explanation-4: -As a result, if the somatic cell has 40 (2n) chromosomes, the haploid gametes will have 20 (n).
