CLASS START 1. What do you think we will study when we study genetics? 2. Who do you look like in your family? 3. Has anyone seen a baby being born of a human or animal? 4. What is probability?
Vocabulary for Genetics Traits: Hybrids: Genes: Alleles: Gametes: Segregation:
CLASS START Flip a coin a your table. Predict how many times it will be heads and how many times it will be tails in the 10 flips. Was your prediction correct? If using probability what should the outcome be? Do you think this is the same for genetics?
Blood Types 1.AB : rarest blood type: universal acceptor 2.B 3.A 4.O : Universal donor; Recessive blood type Cross a male with AB blood type with a female with type A recessive blood. Cross a female with A dominant blood with male B dominant blood.
Practice Punnett Square Problems 1. Cross 2 hybrid tall pea plants. 2. Page 269 question # 5. 3. Brown is dominant in eye color, and blue is recessive. Cross a heterozygous brown eyed person with a homozygous brown eyed person.
