## How many replicated chromosomes are in mitosis?

Once mitosis is complete, the cell has two groups of 46 chromosomes, each enclosed with their own nuclear membrane. The cell then splits in two by a process called cytokinesis, creating two clones of the original cell, each with 46 monovalent chromosomes.

## How many replicated chromosomes are in each cell at the end of meiosis I?

In humans (2n = 46), who have 23 pairs of chromosomes, the number of chromosomes is reduced by half at the end of meiosis I (n = 23).

## How does mitosis maintain 46 chromosomes in daughter cells?

Mitosis is a fundamental process for life. During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells. … When the sperm and egg cells unite at conception, each contributes 23 chromosomes so the resulting embryo will have the usual 46.

## How many chromosomes are in each cell at the end of meiosis II?

At the end of mitosis, the two daughter cells will be exact copies of the original cell. Each daughter cell will have 30 chromosomes. At the end of meiosis II, each cell (i.e., gamete) would have half the original number of chromosomes, that is, 15 chromosomes.

## Are 23 pairs of chromosomes identical?

The nuclei of most human cells contain 46 chromosomes. These 46 chromosomes consist of 23 pairs of homologous chromosomes, or homologs, meaning each of these pairs are alike, but not necessarily identical.

## Do human gametes have 46 chromosomes?

Gametes have half the total number of chromosomes that the organism needs to develop and are referred to as haploid . For example, humans need 46 chromosomes to develop, therefore a human gamete has 23 chromosomes.
