Remember genotype (set of genes in dna) and phenotype (physical expression of: nature vs nurture. Epigenetics: environmental factors can affect physical expression of genes: nature vs nurture. Developmental psychology has been influenced by the nature vs nurture debate. Keep in mind our discussions about scarr and mccartney"s genotype effects (passive genes, active niche picking, evocative reactions child evokes) genes ex eye colour, behavior) Keep in mind the genotype is expressed through the phenotype so we"re really. This ties into our questions about wayne gretzky and mozart - how much has to do with genetic inheritance and how much has to do with environment and the way talking about what triggers a specific phenotype. Simply put what causes a child to exhibit specific behaviours, characteristics and gifts: nature vs nurture. It is also important to consider maturation and experience. Experience is seen as occurring in any settings/situations the child is exposed to from biological to social.
