MITOSIS AND MEIOSIS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
If an wing cell in a butterfly contains 24 chromosomes, a butterfly egg would contain
A
3 chromosomes
B
6 chromosomes
C
12 chromosomes
D
24 chromosomes
Explanation: 

Detailed explanation-1: -If the sperm and egg cells of a butterfly have six chromosomes, 12 chromosomes will be there in the maggot larvae. This is because maggot larvae forms due to the fusion of egg and sperm cells. Since egg contains 6 and sperm cells contains 6 chromosomes, maggot larvae will get both sperm cell and egg cell chromosomes.

Detailed explanation-2: -Thus, the parent cell with 24 chromosomes after undergoing mitosis will form two daughter cells each with 24 chromosomes.

Detailed explanation-3: -If a cell has 24 chromosomes before cell division then daughter cell resulting from mitotic division will have 24 chromosomes while daughter cell resulting from the meiotic division will contain 12 chromosomes each.

Detailed explanation-4: -Complete answer: If a cell has 24 chromosomes and it undergoes mitosis to create two cells, then the daughter cells also have 24 chromosomes each. Mitosis is a process of division of cells where a parent cell divides into two daughter cells each of which is genetically just like the parent cell.
