It varies from species to species.
The human nucleus contains 46 chromosomes.
During meiosis I, each nucleus will have half the number of chromosomes as the original parent cell. This is because meiosis I involves the separation of homologous chromosomes, resulting in two daughter cells with a haploid number of chromosomes.
After DNA duplicates, there are twice the number of chromosomes present in the nucleus.
in pairs
Each new nucleus in Telophase 1 contains a haploid number of chromosomes. This means that each nucleus will have half the number of chromosomes as the original parent cell.
The number of chromosomes in the nucleus before mitosis is dependent on the species. The exact number is called the ploidy of the animal.
Every species has a fixed number of chromosomes in its nucleus so every species has a different chromosome number from the other.
During animal mitosis, each nucleus contains a diploid number of chromosomes. This means that each nucleus in the cell will typically have two sets of chromosomes, with one set inherited from each parent. In humans, for example, this would mean that each nucleus contains 46 chromosomes (23 pairs) during mitosis.
The diploid number of chromosomes in humans is 46. This is identified by counting the number of chromosomes in a cell's nucleus, which contains two sets of chromosomes - one set from each parent.
Yes, that's correct. The number of chromosomes in a nucleus is specific to each species and can vary significantly. For example, humans have 46 chromosomes in each nucleus, while dogs have 78, and fruit flies have 8.

The chromosomes are found in the nucleus.
