Document Summary
Genetics: the study of the mechanism of inheritance. Phenotype: the observable characteristics of an organism. Genotype: the total genetic information carried by an individual. Deoxyribonucleic acid (dna: the molecule that carries the genetic code, types. Chromosomes: a strand of dna in the nucleus of a cell. Gene locus: the point on a chromosome where 2 sets of genetic instructions are found, these sets of genetic instructions are known as alleles. Homozygous: both alleles at a gene locus are the same. Heterozygous: both alleles at a gene locus are different. Alleles at more than one location on the chromosome. Genetic mutation: punnet square, sickle cell anemia. Population: a group of organisms that are capable of forming mating pairs (reproductive unit) Breeding population: a population with some degree of genetic isolation from other populations of the species. Gene pool: the total amount of genetic variability within a breeding population. Discontinuous variation: phenotypic traits are discrete. Continuous variation: phenotypic traits are blended.
