Kia ora, This is my summary of this topic for this term.
Our first thing is DNA is what makes us look different. DNA is what makes us have our colored eyes, our different skin colors, how much hair we have, and our ear shape. DNA carries our genetic code which I will get to soon. Genes are something we get from our descended ancestors or our parents. People may come up to you and say “Oh my goodness, you look just like your father,” While others will say “You are identical to your mother!” That’s how people see us. Some may look more like their dad because their dads genes are stronger. Lets just say their dad has brown eyes and their mum has hazel eyes. If their eyes turn brown rather than hazel it may be because the brown eye genetics might be very strong on the dads side and takes over the mums genetic code. Every gene has different versions of itself and that is called alleles. Allele is two mutated cells that are combined. Inheritance is your parents’ offspring going into you. A Punnett square predicts the allele combos in the parents’ offspring.
A Trait is a characteristic that is decided by our genes. Natural selection is when a living thing choses a significant other that has a better advantage in surviving in the wild with predators. Survival is when animals need to use their resources to survive. Reproduction is when two living things like eachother enough to have a baby together. Evolution is things living on earth changing with the earth and getting to know how the world works.
