As a geneticist with a focus on human genetics, I can tell you that the traits we inherit, such as lip thickness, are determined by the combination of genes we receive from our parents. In the case of lip thickness, it's not as straightforward as a single dominant or recessive gene. Instead, it's a polygenic trait, which means it's influenced by multiple genes, each contributing a small effect to the overall characteristic.

The concept of dominance and recessiveness comes into play when we consider how these multiple genes interact. If a particular gene variant that contributes to thinner lips is more influential or prevalent in a population, it might be considered "dominant" in that context. However, it's important to note that environmental factors and gene-environment interactions can also play a significant role in the expression of traits like lip thickness.

To summarize, lip thickness is a complex trait influenced by multiple genes and is not determined by a simple dominant or recessive pattern. It's a matter of genetic variation and the cumulative effect of many genes, along with environmental influences.
