A Punnett square is used to predict what possible outcomes of a breeding cross or experiment. Genotypes is the genetic makeup of a cell, an organism, or an individual usually with reference to a specific characteristic under consideration. The possible outcomes are GG, Gg, Gg, gg. Homozygous are purebread genes you have three possible outcomes GG, Gg, Gg. Again with heterozygous you have three possible outcomes, Gg, Gg, gg. Adaptation is the process of adapting to a new enviroment. Evolution is 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 are a group of living organisms consisting of similar individuals capable of exchanging genes or interbreeding. Genes are a unit of heredity that is transferred from a parent to offspring and is held to determine some characteristic of the offspring. Genetics are the study of heredity and the variation of inherited characteristics. Sexual reproduction is the production of new living organisms by combining genetic information from two individuals of different types (sexes). In most higher organisms, one sex (male) produces a small motile gamete that travels to fuse with a larger stationary gamete produced by the other (female). Asexual reproduction is a mode of reproduction by which offspring arise from a single organism.
