If an intestinal cell in a butterfly contains 24 chromosomes, a butterfly egg cell would contain ____
A
12 chromosomes
B
6 chromosomes
C
3 chromosomes
D
24 chromosomes
Explanation: 

Detailed explanation-1: -If an intestinal cell in a butterfly contains 24 chromosomes, a butter egg cell would contain what amount of chromosomes? 12 chromosomes. What is one advantage of sexual reproduction? The offspring inherit a wider variety of genetic information.

Detailed explanation-2: -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-3: -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.

Detailed explanation-4: -Chromosome Number A body cell in an adult fruit fly has 8 chromosomes: 4 from the fruit fly’s male parent, and 4 from its female parent. These sets of chromosomes are homologous. Each of the 4 chromosomes that came from the male parent has a corresponding chromosome from the female parent.

Detailed explanation-5: -Egg and sperm cells have just 23 chromosomes each. That’s half as many chromosomes as regular cells. Through the process of fertilization, egg and sperm join to make a cell with 46 chromosomes (23 pairs), called a zygote. For each chromosome pair, one homologous chromosome came from each parent.
