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.
Top 10 facts about the world. A dominant trait is a genetic trait which will manifest when only one copy of the gene is present, overriding another inherited gene coding for a different version of the trait.By contrast, a recessive trait will only appear if an organism inherits a copy of the gene from both parents.n a simple example of the way in which dominant traits work, someone could have two parents who are heterozygous for brown and blue eyes. There is a 25% chance that the child will inherit the bb allele, making him or her blue-eyed.
