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.
The physical appearance of an organism with respect to a trait, i.e. yellow (Y) or green (y) seeds in garden peas. The dominant trait is normally represented with a capital letter, and the recessive trait with the same lower case letter.pleiotropic. A single gene determines more than one phenotype for an organism.oth alleles for a trait are the same in an individual. They can be homozygous dominant (YY), or homozygous recessive (yy). hybrid. heterozygous; usually referring to the offspring of two true-breeding (homozygous) individuals differing in the traits of interest.
