WebSpeculate about the following details of mitosis. 1. Why do chromosomes need to condense during mitosis? 2. Why does the nuclear membrane need to break down at the beginning of prometaphase? 3. Why do chromosomes congress (migrate) toward the metaphase plate during metaphase, and what forces keep the chromosomes there until anaphase begins? 4. WebMitosis produces two genetically identical daughter cells, both of which have the same number of chromosomes as the parent cell. The parent cell divides into two daughter cells, each having half the number of chromosomes as the parent cell, in binary fission.

WebIn metaphase I, each pair of bivalents (two chromosomes, four chromatids total) align on the metaphase plate. This is different from metaphase in mitosis, where all chromosomes align single file on the metaphase plate. The position of each chromosome in the bivalents is random - either parental homolog can appear on each side.

A homologous chromosome pair is known as a tetrad. • Each chromosome pair has two sister chromatids. • Since, there are 2 n = 6 chromosomes means there are n = 3 homologous pairs. As above there are three tetrads lined up in the middle. create a wedding registry on etsyWebHow many chromosomes and chromatids are in the cell? We can see that there are 19 pairs of chromosomes which means there are 38 chromosomes totally present in this karyotype. Chromatids are two arms present in a chromosome.
