Comments of chapter undefined of Nanomancer Reborn - I've Become A Snow Girl?

Today I will try to elaborate on genome and storing of genetic info. So our genetic information is condensed in our genome. It is organised in 46 chromosomes. 44 autosomes ('the bodies chromosomes' and 2 allosomes ('*** chromosomes'). Our chromosomes are all in pairs, because we got half a set from our mother and half a set from our father. This diploid chromosome set is present in all of our cells (Imma exclude all the nitigritty of the sperm and egg cells in my explanation because of word count). This double set serves several roles. First of all it grants genetic diversity because of the combination of two genomes. Second of all it grants some randomness in our genetic diversity, cause nobody can choose which chromosomes are present in his or her reproductive cells, you can't control for example if all the chromosomes are not by some pure instance of luck or badluck all from just one grandparent. And third of all (there are so many more reasons because it's important but you get the gist) we get a failsafe and even different genetic diversity. So to eleborate on that I introduce you the alleles. To put it simply this is a gene (random one) which is present on both chromosomes (normally this is with all genes). So here is the catch what would be if you would be missing a crucial gene? Well you would be dead. But fear not. Nature gave you two copies of the same. It's like contracts, you have one, the other has one, both know the details. The other important point of alleles (the diversity part) is dominant and recessive genes or simple mixtures. So for example when someone has a parent with A blood and another with B blood they can combine and get AB blood or just A or just B depends. The dominant recessive part is little trickier, it means one parent gave you a form of a gene which is preferably active (dominant). For example for mucoviscidose (nasty lethal disease) you need to get two 'less-preferably' active (recessive) forms of the afflicted gene. So both parents must be carriers. If you get one dominant copy, everything is fine (apart from the fact that you are a 'carrier') So that was the first part of genes and genome. I will continue tomorrow. Hope you liked it. Have a delightful day and stay healthy 😉
