Chapter 14 Mendel and the Gene Idea

Law of Segregation:

Chapter 14 Mendel and the Gene Idea Law of Segregation: Two alleles are packaged into separate gametes.

Chapter 14 Mendel and the Gene Idea Law of Independent Assortment:

Chapter 14 Mendel and the Gene Idea Law of Independent Assortment: Each pair of alleles segregates into gametes independently.

Chapter 14 Mendel and the Gene Idea Rules of probability:

Chapter 14 Mendel and the Gene Idea Rules of probability: The probability of a compound event is equal to the product of the separate probabilities of the independent single events.
