Sketch and label diagrams of all phases of Meiosis I and Meiosis II
Answers
Look at the following figure to understand what is the difference
Following are the differences in Meiosis I and Meiosis II in brief:
After DNA replication each chromosome have four sister chromatids(4n). Once entering in meiosis I, chromosome of same type (homologous chromosome) will pair, for example, chr1 of father will match with chr1 of mother (shown in red and blue)
After meiosis I, the two cells formed will have only 1 chromosome of a type, that is either fathers' or mothers' (2 cells with 2n). A point to note is that here the sister chromatids are not separated just the homologous chromosomes separate.
once the cells enter Meiosis II sister chromatids are divided, and thus, in the end, you get haploid cells (4 cells with n).
