Dominant Traits

Dominant traits are traits expressed in individuals with a single copy of the trait's alleles. These traits are expressed over recessive alleles, which means that the trait will show up even if only one parent passes it on. Dominant traits are often studied in genetics to track and trace the inheritance of certain genetic characteristics, such as hair colour and eye colour. Understanding of dominant traits allows geneticists to gain insight into the biological makeup of individuals and study the development of genetic diseases. Dominant traits can also be used in breeding programs to improve and foster desirable traits in certain species, with the aim of making them more resilient or better suited to their environment.
