- Notes on 7.2 - Incomplete and Co-dominance
- Homework (except 1st period): Co-dominance of sickle cell if not completed
- Homework for Tuesday: Complete the di-hybrid crosses.
Monohybrid cross: involves one trait.(Mono=one, hybrid=combination)
Dihybrid cross: two traits.
•Mendel’s dihybrid crosses with heterozygous plants yielded a 9:3:3:1 phenotypic ratio.
Mendel's three conclusions:
-Traits are inherited as discrete units.
Laws of Segregation:
–Organisms inherit two copies of each gene, one from each parent.
–The two copies segregate (separate) during gamete formation.
