Answer:
Co-dominance.
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.
In this scenario, when shorthorn red cattle are bred to shorthorn white cattle, they produce roan (red and white hairs interspersed) offspring. Therefore, this type of inheritance is known as co-dominance because the two (2) alleles (shorthorn red and shorthorn white) are expressed equally or simultaneously in their offspring i.e a roan.
