1. 11-3 Exploring Mendelian Genetics

2. Independent Assortment
The 2 Factor Cross: F1
RRYY x rryy
What does it give us?
The 2 Factor Cross: F2

3. Define Independent Assortment in your own words

4. Mendel’s Principles
Genes are passed on from parents to their offspring
In the case when there are 2 or more alleles for one gene, one may be dominant and one recessive
Segregation of genes happens during meiosis
The alleles that are segregated, segregate independently

5. Incomplete Dominance
One allele is not completely dominant over another

6. Co dominance
Both alleles contribute to the phenotype

7. Multiple alleles
More than two alleles control a trait

8. Polygenic Traits Traits are controlled by 2 or more genes
Eg. Eye color
Skin color (4 genes)
