Objectives, cont. 1. Calculate the probability of obtaining genetic outcomes of given crosses. 2. Apply the sum and product rules of probability in determining genotypic and phenotypic ratios. 3. Determine the gametic genotypes contributed by parental types, monohybrid F 1 progeny, dihybrid F 1 progeny. 4. Identify monohybrid and dihybrid F 2 Mendelian patterns of inheritance.

How did Mendel determine this? Observations of specific types of crosses using a model system. Parental cross: each parent is true breeding (offspring resemble parent in phenotype).
