Mendel’s studies of inheritance patterns in pea plants are a solid foundation for our current understanding of single-gene diseases in humans. Also called Mendelian or monogenic diseases, these kinds of diseases are caused by mutations in one gene, and they sometimes run in families. Pedigree analyses of large families with many affected individuals can be used to determine whether a disease-associated gene is located on an autosome or on a sex chromosome, and whether the related disease phenotype is dominant or recessive.
