Today in class we got our tests back and reviewed things we got wrong. We then started Unit 4 -Genetics. We discussed and practiced Mendelian Genetics finding the phenotype and genotype ratios of the offsprings. We learned about the effect of recessive and dominant traits on the offspring. There are two types of cells, Somatic(body cells) and Gametic(sex cells). We discussed Gametic cells that deal with Meiosis. We learned about the F1 offspring, a carrier, hybrid, pure and backcrossing. We then solved problems dealing with transmission genetics and learned how to do the punnet square to solve it
steps to solving genetic problems
step 1) Write down info
step 2) Parents genotype
step 3) Law of segregation
step 4) Punet square
step 5) fill in info
step 6) Phenotype ratio
Genotype ratio
