Genetics

Genetics

(Science: study) The study of the patterns of inheritance of specific traits. Relating to genes and genetic information. Also known as heredity. Modern theories explain how traits are passed down from parent to offspring. The first to test this theory was gregor mendel, a monk from Austria who tried to explain why some pea plants were short and some were tall, but none were in between. He placed nets over the plants so no bees or flies could pollinate the plants. Pea plants are one of the few plants capable of self pollination, so Mendel tried this with short plants and all were short, so he expected that the same thing would happen with the tall plants. But when he tried it, 75% were tall and 25% were short. This was when he used a punnett Square. A punnett Square is a model used to predict the possible outcomes of offspring.

Chromosome Differences

I am doing a very basic study of genetics/DNA and I finally figured out that the chromosomes are different size and shape because they are made up of different genes, but what I cannot discover is when/how and why the long DNA strand breaks ...
