kia Ora todays blog is about the topics my class has learnt over the term and everything that has happened will be covered in todays blogpost.
DNA: DNA is the fundamental material for humans and other living beings. everybody execpt for twins have the saame DNA like for example if you had a friend that had black hair and you had blonde thats different DNA or genes. DNA is a double helix shape and has its own code built from Adenine Thyimine cytosine guanine (A,T,C,G) these can only be paired with the following: A—T G—C T—A C—G a way to remember this is curved or round shaped letters can be paired with each other and the straight ones can only be paired with straight ones. GENES: Genes are what people inherit like DNA where it has the ability to create what eye colour you are born with for example brown eyes,blue eyes or any other colour. If you had parents that had black hair you would inherit that gene and if a parent was tall while one was short you are most likely to inherit the tall gene. Genes can also be used in another aspect sometimes something can go wrong and you discover you have DWARFISM which isnt a disease but rather a disability in its self but others use this as a good way to view life. ALLELE : Alleles are the different versions of the same gene like blue vs brown eyes if your mother were to have brown eyes and your father had blue eyes you are most likely to inherit the brown eyes because it is most common and because it is what is known as a dominant gene were as blue eyes are recessive genes. INHERIT: Inheriting something is like passing something down to another like if your parents were to pass and had life insurance they would have something for you to inherit when they eventually do pass like for example it could be a house,money,jewelery or something sentimental. But talking about something genetics wise you could inherit the height from your father eyes of your mother or hair colour from your grandparents. PUNNETT SQUARES: punnett squares are like a digital timetable having four squares in the middle and have two letters on the top that go horizontal and two more on the side that go down vertically. It could be like
S s
|——————|
S | SS | Ss |
|———|——–|
s | Ss | ss |
|——————|
ALLELES: Alleles are what creates or helps with the punnett squares because what happenes is the alleles for the genes are usually used for the punnett squares like the S s SS ss Ss could be the probabilities of the outcome like SS is 100%dominant Ss is 50% ss is also 100% but the probabiliy rates are the amount of times it shows on the punnett squares if you have three S and one s the probability is high for SS and if you have three s and one S the probability changes with it becoming Ss because the dominant gene always finds its way. NATURAL SELECTION: natural selection is a saying and its also what happens in real life like if a fox dies from a bear or an apex predator on land its just natural selection because it was bound to die from something in the forest anyways. REPRODUCTION: Reproduction is something that is very common in life and is bound to be seen or done, Reproduction is when two living beings mate and create an offspring but there are certain circumstances where females have created a baby without a mate which is called asexual reproduction sort of like how bacteria clones themselves as a way to Reproduction.EVOLUTION: Evoltuion is a phenomenon that happens when a species doesn’t need a certain trait or when they need it for survival like for example an anteater needs its long tongue for inserting into anyhills and feasting on the ants in there.
