Meiosis allows a cell to form into 4 cells (by meiosis 1 (which is literally mitosis) and meiosis 2 (mitosis without DNA replication))

in meiosis 1, the cells exchanges DNA information between homologous pairs, this allows genes to be transferred and creates 4 unique and distinct cells.

segragation of alleles occur too.

Does the independent assortment of genes during meiosis cause genetic variation?

Yes, the independent assortment of genes during meiosis does cause genetic variation.


How is a linkage related to a cross-overs that take place during meiosis?

The more space there is between two genes on the same chromosome, the more likely it is that crossing over will take place between those two genes. Thus, by studying lots of examples of  meiosis  with crossing over, it is possible to make a map of the chromosome, with the genes (and the relative distances between them) laid out along it.

What hypothesis was the basis of Sturtevant research?

Sturtevant's hypothesis was that the frequency of cross-overs during meiosis was related to the distance between genes


How is trait related to chromosomes and meiosis?

Traits are another name for genes. These are located on various areas of chromosomes. During meiosis, the chromosomes which are duplicated, are formed into gametes (ova or sperm). Those two combine into a new individual with entirely different mixture of traits.


Does crossing over combine or recombine unlinked genes?

Crossing over recombines linked genes by exchanging genetic material between homologous chromosomes during meiosis. Unlinked genes are not affected by crossing over as they are located on different chromosomes and segregate independently during meiosis.


How are crossing over and recombination related?

Genetic recombination occurs during meiosis cell division. As genes cross over during this process, scientists track the genes to study their linkage.


What is the major focus of meiosis?

To mix up the genes to promote genetic diversity


What is meiosis assocuated with?

Activation of meiosis-specific genes is associated with depolyploidization of human tumor cells following radiation-induced mitotic catastrophe.

What assorts independently during meiosis?

Genes assort independently if they are on different chromosomes. If a pair of genes are on the same chromosome, it depends on how far apart they are to determine the chances of them staying together or moving apart.
