A Mendelian trait is one that is controlled by a single locus in an inheritance pattern. In such cases, a mutation in a single gene can cause a disease that is inherited according to Mendel’s principles. Dominant diseases manifest in heterozygous individuals. Recessive ones are sometimes inherited unnoticeably by genetic carriers. Examples include sickle-cell anemia, Tay–Sachs disease, cystic fibrosis and xeroderma pigmentosa. A disease controlled by a single gene contrasts with a multi-factorial disease, like heart disease, which is affected by several loci (and the environment) as well as those diseases inherited in a non-Mendelian fashion.

When working on a problem, don’t start with a solution, start with a problem.
- Describe it as fully as possible.
- Discuss it as thoroughly as possible without giving any solutions.
- Maybe we should have discussed a nail and a horse problem in such manner?
