Question

The mature form of a newly discovered species of eukaryote contains 12 chromosomes and exists in

the diploid state. In this new species. how many chromosomes are present in a mitotic cell immediately
after the sister chromatids have separated?

Answer 1

In a species with a mature diploid number of 12 chromosomes, there would be 24 chromosomes present in a mitotic cell immediately after sister chromatids separate.

Step-by-step explanation:

The question asks how many chromosomes are present in a mitotic cell immediately after the sister chromatids have separated in a eukaryotic organism. During mitosis, a diploid cell contains two sets of chromosomes, and just after the sister chromatids separate in anaphase, each individual chromatid is considered a separate chromosome. Therefore, for a species where the mature diploid number is 12 chromosomes, there would be 24 chromosomes present in a mitotic cell after separation of sister chromatids because each original chromosome is now divided.

Answer 2

12 chromosomes

Step-by-step explanation:

In mitosis the daughter cells finish up with exactly the same number of chromosomes as the parent cell. This is called the diploid condition where the nucleus of each cell contains a pair of each type of chromosome.

The sister chromatids of each chromosome separate at the centromere forming two distinct daughter cells. The eukaryote has 12 chromosomes and exists in diploid state therefore after mitosis, the number of chromosomes will be retained as that of the parent.
