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?

Probability of Offspring’s Gender

Blood Types1. AB : rarest blood type: universal acceptor2. B 3. A4. 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.
