Explore how genetic dominance works between mother and father genes and why dominance varies by trait.
138 views
Neither parent’s genes are universally more dominant. It varies depending on the specific traits and how the genes for those traits interact. For example, eye color can be influenced by both parents, with one parent’s genes potentially being more dominant. Genetic traits are generally a blend of both parents’ contributions.
FAQs & Answers
- Are genes from the mother always more dominant than the father’s? No, gene dominance depends on the specific trait and the interaction of genes; neither mother’s nor father’s genes are universally dominant.
- How does genetic dominance influence traits like eye color? Eye color is determined by multiple genes, and dominance can vary, meaning one parent’s gene may influence eye color more, but it is generally a blend of both parents’ genes.
- What determines which parent’s genes are expressed in a child? Gene expression is influenced by dominant and recessive gene interactions, as well as complex factors such as polygenic traits and environmental influences.
