Ferrets have 40 chromosomes in each heart cell.
There are ___ chromosomes in each egg.
Answer: 20
If a skunk has 25 chromosomes in each gamete, then how many chromosomes are in each sperm cell?
Answer: 25
Sheep have 27 chromosomes in each cell that had undergone meiosis. How many chromosomes are in each stomach cell?
Answer: 54
correct
To determine the number of chromosomes in each egg, you need to consider the process of meiosis. During meiosis, the number of chromosomes is halved. In the case of ferrets, if they have 40 chromosomes in each heart cell, this means that their gametes (eggs or sperm) will have half that number.
So, to find the number of chromosomes in each egg, you divide the 40 chromosomes by 2, resulting in 20 chromosomes.
Similarly, for skunks, if they have 25 chromosomes in each gamete, that means their sperm cells also have 25 chromosomes since they are the male gametes.
Now, regarding the number of chromosomes in each stomach cell of a sheep, it's important to note that stomach cells do not undergo meiosis. Therefore, they maintain the same number of chromosomes as the other somatic cells. If sheep have 27 chromosomes in each cell that has undergone meiosis, we can assume this is the diploid number.
Since each diploid cell has two sets of chromosomes, to find the total number of chromosomes, we multiply the diploid number by two. Therefore, each sheep stomach cell would have 54 chromosomes.
