A cell starts with 12 chromosomes, then goes through mitosis. How many cells are produced at the end of mitosis? How many chromosomes are in each of the cells at the end of mitoses?
A cell starts with 12 chromosomes, then goes through meiosis. How many cells are produced at the end of meiosis? How many chromosome are in each cell of the cells at the end of meiosis?
Double the number of cells with 12 chromosomes.
Double the number of cells with 6 chromosomes.
I'm not sure I understand really.
With mitosis, the number of chromsomes double before the cell splits, leavind the daughter cells with the same species number of chromosomes (diploid).
This duplication does not occur with meiosis, so the daughter cells have only half the original chromosomes (haploid).
I hope that helps.
To answer both questions, we need to understand the process of mitosis and meiosis.
1. Mitosis:
Mitosis is a type of cell division that results in the production of two genetically identical cells, known as daughter cells. Each daughter cell has the same number of chromosomes as the parent cell.
In this case, the initial cell starts with 12 chromosomes and goes through mitosis. At the end of mitosis, two cells are produced. These two cells are genetically identical to each other and to the parent cell. Therefore, each of the two cells will also have 12 chromosomes.
So, at the end of mitosis, there are two cells produced, and each cell has 12 chromosomes.
2. Meiosis:
Meiosis is a type of cell division that is involved in the production of gametes (sex cells) such as sperm and eggs. Meiosis consists of two rounds of cellular division, resulting in the production of four non-identical daughter cells.
In this case, the initial cell starts with 12 chromosomes and goes through meiosis. At the end of meiosis, four cells are produced. These four cells, called gametes, will be genetically different from each other and from the parent cell. The number of chromosomes in the gametes is reduced by half.
During meiosis, the chromosomes undergo a process called recombination, where genetic material is shuffled between chromosomes. As a result, the genetic content of each gamete is unique.
So, at the end of meiosis, there are four cells produced, and each cell will have half the number of chromosomes compared to the initial cell. Therefore, each of the four cells will have 6 chromosomes.
To summarize:
- At the end of mitosis: 2 cells are produced, and each cell has 12 chromosomes.
- At the end of meiosis: 4 cells are produced, and each cell has 6 chromosomes.
