How is crossing over related to variation

Biology
1 answer:
Aloiza [94]3 years ago
5 0
Crossing over occurs in Prophase I of Meiosis I, which occurs between non-winter chromatids of homologous chromosomes. Crossing over results in chiasma being formed, between homologous regions of non-sister chromatids, and synapsis occurs. At Anaphase I, homologous chromosomes separate, and the chiama are broken apart. This results in the previous identical sister chromatids of each chromosome to become non-identical, as the sister chromatid that paired up with the sister chromatid of its homologous chromosomes has a different combination of alleles, which gives rise to different combination of characteristics. Thus, variation occurs in the offspring that attains the sister chromatid (later known as daughter chromosome after Anaphase II).

Hope this helps! :)

<h3>How is the Lewis structure?</h3>

The Lewis structure shows the formation of bonds in a molecule, as well as the atoms involved and the valence electrons of each of them. Atoms form chemical bonds with each other in order to achieve electronic stability.

With this information, we can conclude that Carbon has 4 electrons in its valence shell, thus making 4 covalent bonds.

What might occur if humans reproduced through the process of mitosis?
serious [3.7K]
If gametes were produced instead by mitosis each gamete would be diploid not haploid. During fertilization of diploid gametes, the zygote would become 4n=92. With each new generation the number of chromosomes would double.
