, genotype - 🧠ANSWER ✔✔inherited genetic information that influences trait
acclimation - 🧠ANSWER ✔✔individual adjusting to environmental changes
acclimization - 🧠ANSWER ✔✔changes in observed natural systems
phenotypic plasticity - 🧠ANSWER ✔✔capacity of a single genotype to
exhibit different phenotypes in different environments
plasticity first hypothesis - 🧠ANSWER ✔✔possibility that phenotypic
plasticity might precede and promote adaptive genetic change
genetic assimilation - 🧠ANSWER ✔✔process where a trait was initially
introduced by environmental conditions evolves decreased plasticity and
becomes genetically coded (no longer requires stimulus)
genotype x environment interaction - 🧠ANSWER ✔✔when two genotypes
respond differently to different environments
adaptation - 🧠ANSWER ✔✔when populations become better suited to the
environmental conditions they experience; via heritable change over
generations or geologic time
