Natural Selection - correct answer Depends on the differential success of variants.
Leads to adaptations, which enhances fit between an organism and its

Phenotype - correct answer Observable
2 Factors that contribute to Phenotype - correct answer an individuals genotype
environment individual lives
Population Genetics - correct answer study of patterns of genetic variation (w/in a population)
Species - correct answer group of individuals that can exchange genetic(alleles) materials by interbreeding
Gene Pool - correct answer all alleles present in all individuals in a species
Population - correct answer interbreeding groups of organisms of the same species who live in the same geographical area
2 sources of genetic variation - correct answer mutation and recombination
Mutation - correct answer generates new variation
Recombination - correct answer shuffles mutations to create new combos of mutations(as miosis occurs)
Somatic mutations - correct answer in body tissues
Germ-line mutations - correct answer in reproductive cells(are passed on)
Deleterious mutation - correct answer harmful, random changes to working parts of organized systems
Neutral mutation - correct answer no effect, neither harms nor helps
Advantageous mutation - correct answer help, improve their carriers chances of survival or reproduction
Allele frequencies - correct answer rate of occurrence of alleles in a population
Fixed - correct answer population exhibits only one allele at a particular gene
Evolution - correct answer change in allele or genotype frequency over time
Hardy-Weinberg equation - correct answer when allele and genotype frequencies dont change
evolution does not occur
Fitness - correct answer measure of representation of genotype in next generation
Positive selection - correct answer increases frequency of a favorable allele
Negative selection - correct answer decreases the frequency of a deleterious allele
Balancing selection - correct answer maintaining two or more alleles in a population
Heterozygote advantageous - correct answer form of balancing selection in which the heterozygotes fitnes is higher than both homozygotes [Show Less]
