10. How many chromosomes are in each cell of a chicken?
Answer: Chickens have 78 chromosomes in each cell, including both somatic and germ cells.
To determine the number of chromosomes in each type of cell, we need to understand the process of meiosis and mitosis. Meiosis is the process by which cells divide to form reproductive cells (such as eggs and sperm) that have half the number of chromosomes as the parent cells. Mitosis, on the other hand, is the process by which cells divide to produce identical copies of themselves with the full complement of chromosomes.
1. Ferrets have 40 chromosomes in each heart cell. When it comes to eggs, we need to consider meiosis. Meiosis halves the number of chromosomes in reproductive cells. Since eggs are reproductive cells, they would have half the number of chromosomes as the parent cells. Therefore, each egg would have 40/2 = 20 chromosomes.
2. If a skunk has 25 chromosomes in each gamete (reproductive cell), that means the number of chromosomes in each sperm cell would also be 25. This is because the gametes, whether eggs or sperm, are produced through meiosis, which results in cells with half the number of chromosomes as the parent cells.
3. Sheep have 27 chromosomes in each cell that has undergone meiosis. Stomach cells, however, do not undergo meiosis. They undergo mitosis, which results in cells with the full complement of chromosomes as the parent cells. Therefore, if sheep have 27 chromosomes in each cell that has undergone meiosis, it can be assumed that they have 54 chromosomes in each stomach cell.
