Quantitative genetics

Quantitative genetics, is the study of continuous traits (such as height or weight) that do not have straightforward Mendelian inheritance because they result from the interaction of many different genes.

Modes of inheritance

• Mendelian inheritance includes several different kinds of inheritance:
• Discrete or simple inheritance, is where traits are controlled by a single locus with two alleles
• Multiple alleles where a phenotype is determined by multiple interacting alleles.
• Non-Mendelian inheritance: in non-Mendelian inheritance, traits are not necessarily controlled or inherited according to the Mendelian laws.
