BS 110 Notes 9-15-2010 General Theory of Inheritance Genes determine inherited traits and are transmitted in gametes Individual has a pair of genes in almost every cell for most traits One gene of a pair may differ from the other gene Paired genes (chromosomes) separate during gamete formation and each gamete receives one gene Equal probability that either one of a pair of genes will enter a given gamete (Mendel’s first law) Each pair of genes assorts independently from another pair in gamete formation (Mendel’s Law of Independent Assortment) 2 pairs of genes that occur on separate or different chromosomes
