Principle of Inheritance
Traits are controlled by unit factors (genes). Genes remain intact as they are passed from one generation to the next (they don't blend)
Principle of Dominance
Organisms that have different alleles for certain traits, one allele is always expressed
Principle of Segregation
Different form of unit factors separate during gamete formation (meiosis)
Principle of Independent Assortment
Alleles for traits will randomly assort to form gametes
Genes on chromosomes- chromosome behavior during meiosis and fertilization will predict inheritance pattern
the assumption that parents' traits blended in the child. For example, a tall dad and a short mom would make a medium height child.
True/simple dominance, that if you're heterozygous the dominant allele will show.
Pattern of inheritance where heterozygous show a phenotype that looks like a blend. Neither are strong enough to cover the other.
Certain traits are controlled by multiple alleles. two alleles can be equally expressed in the phenotype.
