Explain the relationship between crossing over and genetic variation.

Here is the sample response:

Crossing over is the process by which genetic material is exchanged by non-sister chromatids during meiosis.  Crossing over results in a new combination of genetic information for the cell for a specific trait.  Crossing over ensures that organisms are not identical from generation to generation.  Genetic recombination allows for a variation in genetic material that is passed through the generations.

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.

answer: i don't know

explanation:

you need to provide a picture, otherwise i can't tell you.

if you can provide one, i'd be more than happy to you with this!
