- Traits are inherited from parents, however they can be influenced by the environment.
- The alleles of a gene make up the genotype and the influencing phenotype. An organism acquires one allele for the gene pair from each parent.
- When both the alleles of a gene pair are similar, the organism is said to be homozygous for the trait. If both the alleles of a gene pair are different, the organism is said to be heterozygous for the trait.
