What do sexual reproduction, mutation, and crossing-over generate in a population

The correct answer is genetic diversity.

Explanation:

During sexual reproduction, two different gametes from two different parents combine to form offspring which is genetically different from their parents. Mutation in the genetic material of germ cell passes to the offspring during fertilization in sexual reproduction which causes genetic diversity or variation.

Crossing- over also helps in generating the genetic diversity because during crossing over genetic material is exchanged between homologous chromosome which changes DNA sequence in chromosome causing variation in gametes.

Therefore sexual reproduction, mutation, and crossing over generate genetic diversity in a population.

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
