Punnett SquarePunnett Squares
In the above punnett square the two genotypes are G and g. The possible outcomes or phenotypes of this punnett square are GG(green flowers), Gg(green flowers), or gg(yellow flowers). In this punnett square the possible homozygous outcomes are GG(green flowers) and gg(yellow flowers). There are two outcomes that are heterozygous that are both Gg(green flowers).
Genotypes and PhenotypesReproduction
During asexual reproduction the offspring will inherit the same genes as the single parent. In sexual reproduction, the offspring will inherit half of their genes from one parent and half from the other parent. This gives the offspring more diverse characteristics since there are twice as many genes that the offspring will receive. Therefore, this will allow for offspring to be more diverse from sexual reproduction rather than asexual reproduction.
Adaptation-a change or the process of change by which an organism or species becomes better suited to its environment.
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 and denoted by a Latin binomial, e.g., Homo sapiens.
Gene- a unit of heredity that is transferred from a parent to offspring and is held to determine some characteristic of the offspring.
Genetic- of or relating to genes or heredity.
Sexual Reproduction- 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- 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. (wikipedia.com)
Animal ClassificationGenetic Variation
Genetic variation helps populations to survive because it allows for species to better adapt to the surroundings and environment. Also, with genetic variation, it is much less likely for offspring to receive a recessive gene that could cause certain diseases. During inbreeding, offspring will become more likely to receive a recessive pair of genes that could cause certain disorders.Therefore, genetic variation will help offspring to survive better since they will be less likely to have defects and will be better suited to adapt.
