Hello, welcome to /asg/ - Actic Science General.
This is where you talk about based science here. The word Actic is just the name of this general.

Genetics, what is it? Well, it's the study of genes. What are genes? Genes are a sequence of nucleotides in DNA or RNA that encodes the synthesis of a gene product, either RNA or protein. Every gene is made up of DNA (Deoxyribonucleic acid) which is a molecule.
DNA is like an instructor, telling the body how it should be and what it should be. Genetics is is like the probability of biology, cause genes are all probability, your hair was more likely due to your mother's/father's hair, or it was random, known as a mutation.
A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light and cigarette smoke. All those stuff, made you who you are.
Genetics is useful for studying evolution and natural selection. It develops for advantage and disadvantage, but the most important part is it's all about probability Some say this is unfair from nature, you choose to be something you don't. Like, for example, let's say you have a low IQ, a disadvantage that let's you be able to process less info from the world than the average person, that's unfair and no one asked for that. There came an idea, by a gene in prokaryotic cells called 'CRISPR-Cas9' which allows for the living thing to have it's gene modified. This was an appealing idea to scientists, we could have a good gene, and replace any bad genes with good ones. It's fairly criticised, some say it's dangerous, and we shouldn't mess with nature at times, some believe it's helpful and that nurture is greater than nature.
This all there's for genetics.
