Question

Quizplus · Accepted Answer

A child's phenotype is influenced by both their genotype (inherited from their parents) and their environment. Genes determine the range of possible traits a child can have, but environmental factors such as diet, lifestyle, and exposure to toxins can also play a role in determining which traits are actually expressed. Therefore, both genotype and environment are direct contributors to a child's phenotype. Parents' phenotype and genotype may indirectly contribute to a child's phenotype through the genes they pass on, but they are not direct contributors.
