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. A monogenic trait is one which is encoded by a single gene. e.g. - cystic fibrosis in humans.
Dominant: A genetic trait is considered dominant if it is expressed in a person who has only one copy of that gene.(In genetic terms, a dominant trait is one that is phenotypically expressed in heterozygotes).A dominant trait is opposed to a recessive trait which is expressed only when two copies of the gene are present. (In genetic terms, a recessive trait is one that is phenotypically expressed only in homozygotes).Examples of dominant disorders include: 1  Achondroplasia (a common form of dwarfism with short arms and legs),In genetic terms, a dominant trait is one that is phenotypically expressed in heterozygotes). A dominant trait is opposed to a recessive trait which is expressed only when two copies of the gene are present.
