Traits-Heredity

http://learn.genetics.utah.edu/

While reading the following information i learned some things. For example, i learned that humans share dna, about 99.9% to be exact. I was shocked, because people look very different from each other. While hearing about heredity, i learned that everyones parents have 23 chromosones, it forms a zygote. The zygote is made of 46 chromosomes, (2 x 23) later on in development it forms a baby. This stage in development is the reason for why one child can look like only a certain parent or a mixture of both parents. In the end i learned many things.
