1. Introduction to Genetics

2. Your envelope has 4 fish Red fish- female traits Blue fish- male traits Work with a partner to determine what the offspring will look like. Time limit- 3 minutes

3. Monohybrid Cross- 1 trait being crossed

4. RR B B

5. RR B B BR

6. Genetics- the science of heredity, study of genes Allele- any of several forms of a gene (a single letter) Dominant- the allele that ‘masks’ the recessive allele Recessive- the allele that is ‘masked’

7. Trait- an inherited characteristic Monohybrid Cross- a genetic cross made to examine the distribution of one specific set of alleles in the resulting offspring. Genotype- the genetic makeup of an organism or group of organisms with reference to a single trait, set of traits, or an entire complex of traits. Phenotype- the appearance of an organism resulting from the interaction of the genotype and the environment.
