Hello readers today I will be going over my entire term of work and all the topics I covered in the term
HOPE YOU ENJOY!!!
Dna (Deoxyribonucleic acid) is a fundamental Molecule that carries our genetic code which is basically our genetic instructions which shows us how we will grow, age and change, it decides what we will look like and how we will come out at the end, For example. Our DNA is what makes us look and act like how we do and its different for everyone. Inside of our DNA is gene which is a small part of it that targets one specific area as in our eyes or hair. Our gene is one specific area of our DNA targeting one area as well, whether that be hair, eyes, height or anything along those terms, For example. If our DNA is like a complete book then our gene is one specific chapter of that book. Our gene is usually chosen between two choices each gene called the allele’s. An allele is the choices that our body makes typically 2 between the father and mother’s traits and we have a chance to get either one though sometimes its very little for some of it, for example. If the gene is a instruction book to how we bake cookies then our alleles are the different variants as in chocolate cookies or normal cookies but instead its our light hair or dark hair instead of something along those lines. We inherit these alleles from both of our parents every time as they basically give part of their genetic code and we inherit either the fathers or mothers side. Inheriting can be near anything whether its looks, personality, smarts or even items all things can be inherited by family members and some times outside of family if its a person giving an item instead, for example. I inherited a lot of money from my father when he passed or I inherited my mothers green eyes but my fathers black hair. We inherit these alleles which can be put into this thing called a punnet square. Punnet squares are these table’s where the input the fathers genes on the top and the mothers genes on the side and laying out the alleles in that order they can list out the chance of the baby getting certain features from each parent essentially guessing what the baby has the highest chance of looking like, for example. The father has the alleles of Bb which has a dominant allele and the mother has the allele’s of aa which are both recessive allele’s when we lay this out on the punnet square,we will found out that the baby has a 25% chance of inheriting the mother’s blue eyes while it has a 75% chance for the father’s brown eyes. These alleles we put on a punnet square can actually create what we call natural selection say when a dog inherit’s the fathers long fur and the other puppy was to inherit the mothers short hair, the short hair pup wouldn’t survive in the cold climate and would eventually not make it to the age needed to reproduce while the pup with long hair would be able to and this is called natural selection.
Natural selection is when the animal with the least suited trait for surviving dies out and the one with the best suited for surviving manage to create offspring which slowly the animals traits will go towards the animals traits making them more likely to survive in where they are being raised, for example. The fathers traits were much better suited for the animals survival so only half of the off spring survived and it was the ones with his traits. However for such a process to happen the father has to live long enough first so that he can even reproduce. Reproduce is when a Female of the species and a Male of the species fall in love or in some cases don’t even fall in love just following instinct reproduce and create babies of the same species and either gender the amount of babies will always nearly vary between species and sometimes even between the same species the amount of offspring will be different as well and this process on repeat slowly causes an evolution. Evolution is when over hundreds of years the species traits become so different they can basically become an entire different species and at times they are counted as a new species, for example. Over the hundreds of years the wolf has been around for thousands of years slowly changing and becoming new species for example huskies which were once wolves but evolved over years and years to become the house pets they are today.
