Group of answer choices( more than 1 can be correct) A. differential survival B. heritability C. variation D. None of the answers are correctA less common but accurate definition of evolution is the change of allele frequencies in an individual. Question 7 a. True b. False
- A common and accurate definition of evolution is the change of an individual’s heritable trait. Question 6 a. True b. FalseRate of evolution by selection is highest for an allele when it is _________ . a. wild type b. recessive c. dominant d. co-dominantWhich must exist in a population before natural selection can act upon that population? A. Genetic variation among individuals B. Variation among individuals caused by environmental factors C. Sexual reproduction D. Three of the responses are correct
- Why is a 'cline' important in explaining some humans variation (like skin color)? (Anthropology question)Population genetics is the study of ________. a. how allele frequencies in a population change over time b. populations of cells in an individual c. the rate of population growth d. how genes affect embryological developmentGenetic variation is the product of completely random events, but acting upon this randomness is a very nonrandom process called natural selection.

FalseThe modes of natural selection differ based on how selection acts on the _____ of a population. a color b environment c genotypes d phenotypesDog breeders use selective breeding, also called artificial selection, to maintain a closed genetic lineage, and produce offspring with desirable traits. This violates which Hardy-Weinberg condition? a reproduction b no mutation c random mating d no natural selection
