This is why siblings within the same family can exhibit a wide range of skin colors, from very light to very dark, a testament to the heterogeneous nature of their ancestry. Individuals inherit a complex combination of genes from their parents that regulate this process.
The indigenous Taíno people, who originally inhabited the island, formed the foundational layer. The presence of multiple ancestral backgrounds means that Dominican genetic heritage includes variants associated with high melanin production and variants associated with lower production.
