PRESENTATION OUTLINE
Traits: a distinguishing quality or characteristic, typically one belonging to a person.
Heredity:the passing on of physical or mental characteristics genetically from one generation to another.
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: is a type of reproduction by which offspring arise from a single organism, and inherit the genes of that parent only; it does not involve the fusion of gametes and almost never changes the number of chromosomes.
Genes: (in informal use) a unit of heredity that is transferred from a parent to offspring and is held to determine some characteristic of the offspring.
Chromosomes: a threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes.
DNA:deoxyribonucleic acid, a self-replicating material present in nearly all living organisms as the main constituent of chromosomes. It is the carrier of genetic information.
Genotype: the genetic constitution of an individual organism.
Phenotype: the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment.
Phenotype: one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome.
