Answer:
Co-dominance
Step-by-step explanation:
Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.
In Genetics, co-dominance can be defined as a phenomenon in which two (2) alleles of the same gene are present in a living organism and both are equally expressed to a degree or simultaneously.
This ultimately implies that, co-dominance is a phenomenon that typically involves the relationship between alleles i.e the two (2) versions of a gene present in living organisms. Also, a single version of a gene expressed by a living organism is referred to as an allele.
Hence, if there are three phenotypes present: Red, White, and BOTH RED AND WHITE, that means that the heterozygous shows both traits and you can think of it as having two "dominant" traits. This is an example of co-dominance.
