Recall that there are two divisions during meiosis: meiosis I and meiosis II. The genetic material of the cell is duplicated during S phase of interphase just as it was with mitosis resulting in 46 chromosomes and 92 chromatids during Prophase I and Metaphase I.
How many chromosomes and chromatids are at the end of meiosis 1?
The process of meiosis involves two divisions of the genetic material. The first division is called the reduction division – or meiosis I – because it reduces the number of chromosomes from 46 chromosomes or 2n to 23 chromosomes or n (n describes a single chromosome set).
How many chromosomes and chromatids are in each stage of meiosis?
During meiosis II, each cell containing 46 chromatids yields two cells, each with 23 chromosomes. Originally, there were two cells that underwent meiosis II; therefore, the result of meiosis II is four cells, each with 23 chromosomes.
How many chromosomes do daughter cells have after meiosis 1?
A human cell has 46 total or 23 pairs of chromosomes. Following mitosis, the daughter cells would each have a total of ______ chromosomes.
Problem 1: Number of chromosomes.
|A.||46, 46, 46|
|D.||46, 12, 12|
How many chromosomes are at the end of meiosis?
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.
What is the ploidy of the DNA at the end of meiosis I?
The ploidy of the DNA at the end of meiosis I each of the two daughters are haploid. At the end of meiosis II, each of the 4 daughters are also haploid. Why do you use non-sister chromatids to demonstrate crossing over?
How many chromosomes are in anaphase 2 of meiosis?
In the anaphase cell, there are 8 chromosomes. The resulting daughter cells will also be diploid and genetically identical to the mother cell. This is a haploid cell in metaphase and anaphase of mitosis.
