G= Green Flower g= Yellow Flower

From the above punnett square, the two genotypes are Gg and Gg. All possible outcomes are GG= Green Flower, Gg= Green Flower, and gg= Yellow Flower. Therefore you have two homozygous (GG and gg) and two heterozygous (Gg and Gg).

Sexual reproduction have more diverse characteristics than asexual reproduction because asexual reproduction generates offspring that are genetically identical to a single parent while sexual reproduction has two parents contribute genetic information to produce unique offspring.

Adaptation- the ability of a species to survive in a particular ecological niche, especially because of alterations of form or behavior brought about through natural selection.

Evolution-  change in the gene pool of a population from generation to generation by such processes as mutation, natural selection, and genetic drift.

Species- the major subdivision of a genus or sub genus, regarded as the basic category of biological classification, composed of related individuals that resemble one another, are able to breed among themselves, but are not able to breed with members of another species.

Gene- the basic physical unit of heredity.

Genetic- pertaining or according to genetics.

Sexual Reproduction- reproduction involving the union of gametes.

Asexual Reproduction- reproduction, as budding, fission, or spore formation, not involving the union of gametes.

The survival value of of genetic variation is important because  when a population of an organism contains a large gene pool, the group has a greater chance of surviving and flourishing than a population with limited genetic variability.
