Homozygous
- states that the inheritance of one allele pair is independent from that of the other allele pairs.
Law of Dominance
Law of Segregation
Law of Independent Assortment
- states that in a heterozygous individual, only one allele will be expressed (dominant), and the other one will be masked (recessive).
Law of Dominance
Law of Segregation
Law of Independent Assortment
