1.  The two genotypes are Gg and Gg.

2.  The phenotypes would be 3 plants with green flowers and one plant with yellow flowers.

3.  There would be 2 homozygous outcomes - 1 would be homozygous dominant (GG) and the other would be homozygous recessive (gg).

4.  There would be 2 heterozygous outcomes (Gg).

5.  Sexual reproduction provides genetic diversity because the sperm and egg that are produced contain different combinations of genes than the parent organisms. Asexual reproduction, does not need sperm and eggs since one organism splits into two organisms that have the same combination of genes. Sexual reproduction involves meiosis, which is the process of a cell doubling its DNA, shuffling its genes, and then dividing the shuffled DNA among four cells. Each resulting cell, or gamete, resulting from meiosis has only half the amount of DNA as the parent cell. So in order to form a new organism, two gametes -- the sex cells, sperm and egg -- must fuse, further mixing the genes to produce more genetic diversity. Asexual reproduction is one organism dividing into two organisms without shuffling its genes, so the offspring has the same version of genes as did the parent.

Adaptation - process by which an animal or plant species becomes fitted to its environment; it is the result of natural selection’s acting upon heritable variation.  Organisms seem to accumulate certain physiological, behavioral, and structural traits gradually, and these traits aid them in their ability to survive and reproduce under existing environmental conditions.

Evolution - the process by which different kinds of living organisms are thought to have developed and diversified from earlier forms during the history of the earth.

Species - a group of living organisms consisting of similar individuals capable of exchanging genes or interbreeding. The species is the principal natural taxonomic unit, ranking below a genus.

Gene - a unit of heredity that is transferred from a parent to offspring and is held to determine some characteristic of the offspring.

Genetic - the science of heredity, dealing with resemblances and differences of related organisms resulting from the interaction of their genes and the environment.

Sexual Reproduction - a biological process that creates a new orgnaism by combining the genetic material of two organisms in a process that starts with meosis, a specialized type of cell division. Sexual reproduction is the primary method of reproduction for the vast majority of macroscopic organisms, including almost all animals and plants.

Asexual Reproduction - a mode of reproduction by which offspring arise from a single organism, and inherit the genes of that parent only; it is reproduction which almost never involves ploidy or reduction. The offspring will be exact genetic copies of the parent, except in the specific case of automixis.

Genetic diversity serves as a way for populations to adapt to changing environments. With more variation, it is more likely that some individuals in a population will possess variations of alleles that are suited for the environment. Those individuals are more likely to survive and to produce offspring bearing that allele. The population will continue for more generations because of the success of these individuals.

Genetic diversity plays an important role in the survival and adaptability of a species. When a population's habitat changes, the population may have to adapt to survive; the ability of the population to adapt to the changing environment will determine their ability to cope with an environmental challenge. Variation in the population's gene pool provides variable traits among the individuals of that population. These variable traits can be selected for, via natural selection, ultimately leading to an adaptive change in the population, allowing it to survive in the changed environment. If a population of a species has a very diverse gene pool then there will be more variety in the traits of individuals of that population and consequently more traits for natural selection to act upon to select the fittest individuals to survive.

Genetic diversity is essential for a species to evolve. With very little gene variation within the species, healthy reproduction becomes increasingly difficult, and offspring are more likely to have problems resulting from inbreeding. The vulnerability of a population to certain types of diseases can also increase with reduction in genetic diversity. Concerns about genetic diversity are especially important with large mammals due to their small population size and high levels of human-caused population effects.
