Laws of Inheritance
The Law of Segregation
Purple and white flowers produced both purple and white plants in F2.
F1 hybrids, hidden white flower plant trait.
3:1 ratio by F2 generation.
Didn't produce pale purple plants, blending theory doesn't apply.
The Law of Independent Assortment
Worked out by following two characters, dihybrids.
States each pair of alleles segregate independently from others.
Only pertains to genes on different chromosomes or far apart on same one.
Organism w/ unknown genotype crossed w/ homozygous recessive.
Types of Dominance
