1) A trend I noticed was that in each graph, there was a big group with the same size, or the average size. For example, one graph bar was always much larger than the rest.
2) Overall, only about 3 people had extreme traits varying between below average and above average.
3) A trait with most variation was probably the hand span.
4) Having variation benefits species because if they were all the same, they would not only require a tremendous amount of the same food but it would also only take one thing to weaken or even kill all of the population of that species.
5) Having extreme traits can be very beneficial to the species because they are able to accomplish what a average could not do. It adds variety. For example, there are giraffes with long necks, average necks and short necks. this means that the tall giraffes can get the tall trees while the short giraffes can get food closer to the ground.
6) I have the characteristics I have because of the genes my parents gave me. These genes result to the way I look and the way I act. For example I am tall because both my parents are tall, I have big brown eyes from of my mother, and I have thick brown hair from my father.
7) A gene is a unit of heredity that is transferred from a parent gene to an offspring.
A DNA (Deoxyribonucleic acid) is a self- replicating material located in the cell nucleus and is in
