1. Genetics Notes

2. Gregor Mendel Father of genetics Pea pod experiments

3. Traits and Inheritance Traits: Specific characteristics of an individual that can vary P: parent generation F 1 : filius/filia Hybrids: offspring that results from genetic combination of both parents Alleles: different forms of a gene Some are dominant forms, some are recessive forms

4. Punnett Squares Deal with probabilities Show possible genetic combinations that offspring can inherit Homozygous: organisms that have two identical alleles for a trait (can be dominant or recessive) Heterozygous: organisms that have two different alleles for a trait

5. Punnett Squares Phenotype Physical characteristics The physical expression of an organisms DNA Genotype Genetic makeup Represented by two of the same letters in Punnett Squares

6. Monohybrid Crosses Possible outcomes:
