Meiosis
When does crossing over occure?
Crossing over occurs during prophase I of meiosis before tetrads are aligned along the equator in metaphase I. By meiosis II, only sister chromatids r...
In what situations is meiosis used by organisms?
Multicellular eukaryotes, like humans, use mitosis to grow or heal injured tissues. Meiosis, on the other hand, is a specialized form of cell division...
Where does meisosis take place?
During fertilisation, two haploid gametes fuse to form one diploid cell. This will divide by mitosis to form an organism. Meiosis occurs in the testes...
Which of the two meiotic divisions is similar to the first mitotic division?
Two divisions, meiosis I and meiosis II, are required to produce gametes (Figure 3). Meiosis I is a unique cell division that occurs only in germ cell...

How does the number of Genesis and I sex cells differ from the number of Genesis and other types of cells found in organisms?
How do the final products of meiosis differ in reproductively capable humans that produce sperm versus eggs?What is the difference between sex cells ...
How does meiosis generate enormous variability?
Genetic variation is increased by meiosis Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA....

What happens in miosis?
Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. ... During me...
