Sequence of nucleotides that codes for a polypeptide and is the unit of inheritance - Gene, Different forms of a gene - Allele, Describes an allele that is expressed in all conditions - Dominant, Describes an allele that is expressed only when both alleles are the same - Recessive, Condition of having two identical alleles for a particular gene - Homozygous, Condition of having two different alleles for a particular gene - Heterozygous, Combination of alleles for a particular gene - Genotype, Expressed (observable) trait of the individual - Phenotype, During gamete formation, each gamete only receives one copy of each gene - Mendel's Law of Segregation, Pair of chromosomes with the same sequence of gene loci, one from the mother and the other from the father - Pair of homologous chromosomes, Due to the additive effect of multiple genes; trait has intermediate forms - Continuous variation, Controlled by one or few genes; trait has few or no intermediate forms - Discontinuous variation, Process in which organisms with desirable genes and phenotypes have a higher chance of surviving and passing on their genes to their offspring - Natural selection, Interaction between organisms to obtain resources that are limited in supply - Competition, Group of individuals of the same species living and interacting with one another in the same habitat - Population, Organism that is homozygous for a specified trait - Pure-bred, Differences in traits between individuals of the same species - Variation, Change in the sequence of a gene or in the chromosome number - Mutation, Gradual change in the inheritable characteristics of a population over time - Evolution,
