"WebbIn simple traits, the variations within the gene usually create major changes in the way the gene's product (the protein it codes for) acts. In most cases, these changes (mutations) are considered causative, because having them is enough to cause the disease. In other words, having the mutation is sufficient to get the disease.

WebbOverview. In biology, a character is an attribute of an organism that allows it to be compared with another. In genetics this refers to heritable features which can exist in more than one state. A trait is a distinct phenotypic character of an organism that may be inherited, environmentally determined or somewhere in between. For example, eye color … WebbAlthough many traits observe the 3:1 inheritance rule that Mendel uncovered, some traits behave as co-dominant traits, in which the F1 phenotype is intermediate between the two parental types.
