An allele is a version of a gene. For example, in fruitflies there is a gene which determines eye colour: one allele gives red eyes, and another gives white eyes; it is the same *gene*, just different versions of that gene. A monogenic trait is one which is encoded by a single gene.e.g. - cystic fibrosis in humans.There is a single gene which determines this trait: the wild-type allele is healthy, while the disease allele gives you cystic fibrosis.or example, in fruitflies there is a gene which determines eye colour: one allele gives red eyes, and another gives white eyes; it is the same *gene*, just different versions of that gene.

Polygenic inheritance. Definition. noun. A non-Mendelian form of inheritance in which a particular trait is produced by the interaction of many genes.Supplement.Polygenic inheritance refers to the kind of inheritance in which the trait is produced from the cumulative effects of many genes in contrast to monogenic inheritance wherein the trait results from the expression of one gene (or one gene pair). non-Mendelian form of inheritance in which a particular trait is produced by the interaction of many genes.
