How DNA as genetic materials was established (also summarized in er including structure and components Basic properties of DNA, i xt slide)

Linkage: Alleles of two genes segregate together during meiosis

Extensions of Mendelian Analysis Interactions between alleles of one gene. Multiple alleles, incomplete dominance, codominance Interactions between alleles of two genes. New phenotypes, epistasis Relationship between genotype & phenotype lethals, variable penetrance, conditional alleles

Cells reproduce via a cell cycle Meiosis is the key to sexual reproduction and Mendel’s rules Sex determination, sex linkage and chromosome nondisjunction supported the chromosome theory

Genetics is a different biology class Reading, attending lectures Andunderstanding the concept-notmemorizing Do problem sets

Restriction enzymes are used for cutting DNA at precise locations Vectors are used for the propagation of cloned DNA fragments Libraries of cloned DNA fragments allow searching for a specific DNA fragment
