To start today two groups presented their slide shows. After that we reviewed the questions that we had to do in class yesterday with a partner. I learned that single celled organisms go through binary fission. During the review of the questions someone asked if there's male and female bacteria and immediatly he noticed that the answer was no. Mr. Finley showed us karyotypes which are pictures of our chromosomes. We also saw autosomes which carry almost all of our traits. There are 44 kinds and 22 pairs. For sex chromosomes if there's xx your a girl if there's xy your a boy. There are 46 chromosomes. 23 from your mom and 23 from your dad. There are 23 homologous pairs. In a chromosome one side is a chromatid and the other side is another chromatid. That's for x shaped chromosomes.
