Independent assortment of traits and chromosomes demonstrated by dihybrid crosses with two traits.

Morgan's experiments with fruit flies showed linkage between two genes/traits. Dihybrid crosses with two traits show genetic recombination and genetic distances.

Sturtevant's work with multiple traits mapped out genes on chromosomes based on recombination frequencies. Genetic maps allowed biologists to predict frequency of double recombination.

X and Y chromosomes determine gender. In fruit flies, certain physical traits such as eye color lie on the X chromosome and are linked to the sex of the fly.

Eukaryotes and prokaryotes vary in DNA replication due to differences in chromosome structure and genome sizes.

The discovery of chromosomes and brief overview of meiosis in the context of Mendel's work. Chromosome theory of inheritance-traits are carried on chromosomes that segregate when gametes form.
