The carp fish has 104 chromosomes in its body cells. When the fish's body cells divide by mitosis, how many chromosomes will each daughter cell have?
A.
104
B.
52
C.
312
D.
208
To determine how many chromosomes each daughter cell will have when the carp fish's body cells divide by mitosis, we need to understand how mitosis works. Mitosis is the process by which a single cell divides into two identical daughter cells. During this process, the chromosomes are replicated, and then the cell divides, ensuring that each daughter cell receives a complete set of chromosomes.
In the case of the carp fish, it has 104 chromosomes in its body cells. When mitosis occurs, the chromosomes are duplicated, so there are now two copies of each chromosome. These duplicated chromosomes are called sister chromatids. During mitosis, the sister chromatids are separated, and each daughter cell receives one copy of each chromosome.
Therefore, the correct answer is:
A. 104
Each daughter cell resulting from mitosis will have 104 chromosomes, just like the original cell.
