In class we first started out by discussing our homework with our new seating chart and groups that Mrs. Stein arranged for us. After our discussion with our peers we went over the correct answers as a class and discussed any of the questions that were kind of weirdly worded and tricky. After going through the answers we got into more detail with Blood typing and sex linked problems, especially the hybrid blood types.
Please ignore the names mentioned in the Pedigree above..... However the main lesson of today was Pedigrees. What are Pedigrees? They a chart made up of family members from one generation continuing on till the current. Pedigrees are used to trace disease or a specific trait within a family. Males in the chart are shown as Squares, and Females are shown as circles. However people that are shaded in have that trait or disease the is being tracked, women however with a half shaded circle are carriers of the disease or trait and may pass it on to one of their children and so on.
HOMEWORK!
- UP 47-50
- Read Chapter 14.1 in the textbook ( no duh where else?)
- Quiz on how to solve all of the punnet squares and problems on how to find a genotype and phenotype ( codominance etc.), Pedigrees will also be on the quiz!
