- Mendel's laws are fundamental laws of genes.
- The substance of genes is DNA.
- Genetic information is transmitted, in order, by DNA, RNA, and proteins.
- All DNA sequences necessary to form any given organism are collectively called genome. Genes are a part of genomes.
- Biologically, there are various forms of sexes.
- Genetic recombination occurs during gamete formation.
- The repetition of replication and mutation of genomes are the driving force of diversity and evolution of life.
