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

Explanation:

Genotype-enviroment correlation occurs when exposure to environmental  conditions depends on a person's Genotype

Active genotype enviroment correlation occurs when a child possesses a heritable talent that influences their selection to an environmental exposure.

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.

hey bro i looked it up on google the structure of the eye-spot in euglena viridie, e. ehrenbergii, and phacus pyriyorme is not as franzé haa described it. the so-called “crystal body” and “lens bodies” were not found in any of the individuals of the species examined by me. as earlier observers have stated, the eye-spot consists simply of a mass of pigment granules arranged in a single layer, and probably embedded in a protoplasmic framework, but the latter could not be seen, and its presence was only inferred from the fact that the pigment granules must be held together in some way, thd the eye-spot as a whole is capable of expansion, and that the pigment granules can be separated from each other.

hope this   and an i get brainlsiest
