Allison learned that she had a good singing voice in childhood. She requested vocal lessons, and now she participates in the school choral program. This is an example of which type of genotype-environment correlation?

Active genotype enviroment correlation

For Example Allison's singing was heritable since it started from childhood. She requested to go for vocal classes and now participates in school choral programs. Due to her talents, she tends to like being in an environment that correlates her genotype.

relative humidity, temperature and dew point -- are bound together in the mathematical relationship below. relative humidity changes when temperatures change. because warm air can hold more water vapor than cool air, relative humidity falls when the temperature rises if no moisture is added to the air. so i would say a
