Punnet Square

In the above Punnet square the genotypes are GG, Gg and gg. Capital G being dominant and lowercase g being recesive. The possible outcomes are three green flowers and one yellow flower. There is two homozygous (GG and gg) and two heterozygous (Gg and Gg).

Asexual reproduction passes down offspring the is gentically identicle to the single parent. In sexual reproduction, two parents contribute genetic information to produce unique offspring.

Adaption: The action or process of adapting or being adapted.
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.
Speices: A group of living organisms consisting of similar individuals capable of exchanging genes or interbreeding.
Gene: A unit of heredity that is transferred from a parent to offspring and is held to determine some characteristic of the offspring.
Genetic: Genetics is the study of genes, heredity, and genetic variation in living organisms.
Sexual Reproduction: Sexual reproduction is a biological process that creates a new organism by combining the genetic material of two organisms in a process that starts with meiosis, a specialized type of cell division.

Animal Classification

Genetic diversity is important because if every organism in every species was exactly the same everything would be different and would not  function properly.

Plants are asexual
polar bears are a species
Whales sexually reproduce offspring
