So the first thing we did when class started was get our stamps for last week's homework.
But as we Mrs. Stein was walking around class giving stamps we talked to our group members, people sitting nearby us, about the homework and helped one another out! Last week's homework was to solve punnet squared for sex linked and multiple alleles. If you need more help on these then check out Julia's post!
Then we went over the answers.
We also reviewed what the different hybrid blood types!
Our new lesson is on Pedigrees!! This is a good example of a pedigree chart. Pedigrees are used to trace a disease, or a certain trait, through a family. Males are as shown above represented by a square and females are represented as a circle. Individuals that are affected by the disease or trait are shaded in. In a sex linked problem carrier females are shown as half shaded circles.
We also have a quiz on Thursday and we must know how to solve all the different punnet squares. If you need help then you can do UP 53-56. The answers will be posted on Moodle if you need them. There will be similar problems that will come up in the quiz! So study!!
For homework today we have to do....
- UP 47-50
- Read 14.1 (IF YOU DIDN'T READ IT THIS WEEKEND. But you can read it for fun as well!!)
- WE HAVE A QUIZ THURSDAY!!
