Explanation:
Chromosomes are visible only in reproduction otherwise they are in thread like structure called chromatin. Almost all nucleated cells contain chromatin or chromosomes while non-nucleated cells don't have chromosomes because chromosomes are always present in nucleus. Non-Nucleated cells include Red Blood Cells and thrombocytes.
When mitosis is finished, a cell that had 12 replicated chromosomes at the beginning will still have 12 chromosomes.
<h3>has 12 chromosomes in a cell? After mitosis, how many chromosomes will be present in each of its daughter cells?</h3>
If the cells have 12 chromosomes during interphase, they will still have 12 in each of their daughter cells even after mitosis is complete.
<h3>At the start of meiosis, do cells have 12 chromosomes? At the conclusion of meiosis, how many will there be?</h3>
Meiosis is a cell division process in which a single parent cell divides twice to produce four daughter cells that each have half as much genetic material as the original cell. Therefore, if a cell has 12 chromosomes at the start of meiosis, then 12/2=6 chromosomes will be present in the cell by the completion of meiosis.
