Try out the Hardy-Weinberg Simulator. Chromosome structure and function. Mechanisms of chromosome division and segregation lead to severe mutations. Yet plants, particularly agricultural crops, are often polyploid. Animal and plant models of disease.
Transgenic plants reveal surprising affinities to human physiology.
Bacterial DNA operates by unique mechanisms, including the promiscuous spread of genes for virulence and drug resistance. Traits in nature always combine many influences of genes and environment. Over time, change in DNA sequence leads to new genes and new species. Molecular evolution explains the structure of mitochondria, and the dimorphism between X and Y chromosomes. Science fiction genetics.
