1 LEVEL ZERO VOICE POP QUIZ (4 minutes, individual work): 1. Define gene: 2. Define phenotype: 3. A heterozygous white rabbit is crossed with a homozygous black rabbit.

2 LEVEL ZERO VOICE POP QUIZ (4 minutes, individual work): 1. In the image shown, G/g represents the gene for the protein lactase. A "G" indicates an allele that causes continual production of lactase. A "g" indicates an allele that causes lactase to be produced only infants, not adults. Lactase tolerance is a dominant inherited trait. What is the genotype of "A" (case sensitive): 2. Which of the genotypes that would be in the letters below are homozygous? Select all that apply. 3. What are the chances that an offspring will be lactose intolerant? 4. These two people who are mating decide to have a lot of babies. They have 120 babies!!! How many do you expect to be: Lactase persistent (write number here): Lactase nonpersistent (write number here):

In humans, the ability to roll the tongue is a dominant trait. The inability to roll the tongue is a recessive trait. If two individuals homozygous recessive for this trait have a child, what is the chance that the child will be able to roll his tongue? 4. The Punnett square above shows a genetic cross between two tall pea plants. (Phenotype is tall, Genotype is heterozygous Tt). If 75% of the offspring are tall, what type of inheritance occurred?

4 What is a case study? A case study is about a person, group, or situation that has been studied over time. [1] If the case study, for instance, is about a group it describes the behavior of the group as a whole, not the behavior of each individual in the group. Case studies can be produced by following a formal research method.
