Homework Answers
answer) firstly the homologus chromosomes come close each other and than formation of bivalent occur than the crossing over between these homologous chromosomes will occur than these get align in the equator of the cell. and lastly the seperation of homologous chromosome. so the answer will be 2,3,4,1.

Crossing-Over in Meiosis Meiosis is a process of nuclear division that reduces the number of chromosomes in new cells to half the number in the original cell. The parent cell is diploid (2n), and it begins meiosis with a replicated set of chromosomes. During meiosis, this parent cell Homologou will divide twice to create four haploid (1n) cells. pairs During prophase I of meiosis I, homologous pairs of chromosomes pair up and stick together to form tetrads through the process...
