How do genes have an additive effect in polygenic inheritance? Select all that apply

Genes diversify to create several discrete phenotypes

A single gene with many alleles determines the phenotype

The number of possible phenotypes can add up until there is a continuous range of phenotypes

Each gene contributes a small part to the phenotype

Describe the change in phase and temperature as water moves from the oceans to the atmosphere and then returns to earth again as rain. a) evaporation : temperature increases; condensation : temperature decreases; precipitation (rain) : temperature decreases b) evaporation : temperature increases; condensation : temperature decreases; precipitation (rain) : temperature increases c) evaporation : temperature decreases; condensation : temperature decreases; precipitation (rain) : temperature decreases d) evaporation : temperature increases; condensation : temperature increases; precipitation (rain) : temperature decreases
