4.1 Simple Inheritance Patterns
Simple mendelian: inheritance of alleles obey Mendels laws and follow a strict dominant/recessive
Incomplete dominance: heterozygote has a phenotype that is intermediate between either
3.1 General Features of Chromosomes
Chromosomes are structures within living cells that contain genetic material, complex between DNA

Chapter 7 (and 19) Linkage and Mapping Part III
This chapter will study the genetics of bacteria
Bacteria produce asexually so genetic crosses are not used in analysis; rather, researchers rely on a
method known as genetic transfer in which a segment of b
