Best Answer

In meiosis, genes crossover, there is independent assortment (each pair of alleles segregates independently of each other pair of alleles during gamete formation), and the law of segregation (the two alleles for a heritable character segregate during gamete formation and end up in different gametes (daughter cells)). In meiosis, what genes an offspring inherits from each parent is decided. In humans, there are at least 8 million different variations of children.

This is part of sexual reproduction, and creates half of the genetics to be combined with half of the other parent organism's genetics. Like in humans, it would contain 23 of out 46 chromosomes, which are made of our DNA. This means that it would cross qualities from two separate and different creatures from the same species.

Mutations are very important for evolution today because they usually lead to the genetic changes in a given gene pool. They also allow the species to change with the environment.


What molecule is used to store genetic information?

Which type of pollination is better self or cross pollination?

Both types of pollination have advantages. Self pollination allows a plant to reproduce even if there are no other plants of the same type nearby. Cross pollination can serve to prevent the extinction of a species due to a lack of genetic variation.


What protein structure moves chromosomes?

During mitosis and meiosis, kinetochores move chromosomes across the spindle fibers. The kinetochores serve as vehicles and the fibers serve as roads.

What is the function of the chromatin in a plant?

Chromatin is the complex combination of DNA and protein that makes up chromosomes. The functions of chromatin are to package DNA into a small volume to fit in the cell, to strengthen the DNA to allow mitosis and meiosis, and to serve as a mechanism to control DNA expression and replication. Chromatin contains genetic material - instructions to direct cell functions.
