This picture shows anaphase of mitosis.
The centromere of every chromosome is seen dividing. Sister chromatids are separated and are moving towards the poles.
The diploid number of the cell =2n=2×4=8 chromosomes in the anaphase stage as it is doubled
Where n= number of chromosome
But in the prophase and metaphase number of chromosomes in 4.

Meiosis is composed of two chromosomal division called Meiosis I and Meiosis II. Each of the two divisions consists of Prophase, Prometaphase, Metaphase, Anaphase and Telophase and each of these phases is designated I or II according to which division it is a part of. Be sure you know what happens in each phase in regard to the chromosomes, chromatids, spindles and the nuclear envelope. During which phase does synapsis occur and crossing over begin? And in which division, Meiosis I or Meiosis II...

Can someone please check my answer? Understanding chromosome number and behavior during cell division is an important concept in genetics. Fill out the chart below for each phase of mitosis in terms of N (where N = haploid number). For example, humans have a haploid number of 23. There are 46 chromosomes (2N) present in prophase of mitosis. Each chromosome is present in its replicated form (i.e. as sister chromatids) so there will be 2 chromatids per chromosome and the...

Simulate meiosis by drawing Two pairs of chromosomes with crossing over Assume that two of the genes are on chromosome 1, and one of the genes is on chromosome 2. Allow crossing over to occur between the two genes on the same chromosome. Also, are there multiple ways that the chromosomes could segregate to produce different results? Show them. Instructions: Set up your cell. The cell you start with should be: A diploid cell It should contain 2 pairs of...
