Explanation:
Detailed explanation-1: -192. During mitosis, a cell duplicates its chromosomes and then divides into two identical daughter cells. Each daughter cell will have the same number of chromosomes as the original cell. Since a goldfish cell has 96 chromosomes, after mitosis, each daughter cell will also have 96 chromosomes.
Detailed explanation-2: -Goldfish (Carassius auratus), one member in the Cyprinidae family, has twice the number of chromosomes (n = 50) than zebrafish (n = 25).
Detailed explanation-3: -If goldfish mated without gametes first undergoing meiosis, the resulting total chromosome number would be 188. This is because, under normal conditions, the total number of chromosomes in the goldfish diploid cell is 94.
