Adaptation - correct answer Inherited characteristic of an organism that enhances its survival and reproduction in specific environments
Natural
... [Show More] selection - correct answer A process in which organisms with certain inherited characteristics are more likely to survive and reproduce than are organisms with other characteristics.
Artificial selection - correct answer The selective breeding of domesticated plants and animals to encourage the occurrence of desirable traits
Observations of change, fossil record, homology, biogeography - correct answer 4 Supporting Lines of evidence for Evolution
Analogy - correct answer The similarity of two species due to convergent evolution. These species have similar characteristics because they live in similar environments
Homology - correct answer Similarity in shared characteristics because of shared common ancestry
Population - correct answer What is the smallest biological unit evolution can affect?
Mutation - correct answer What is the ultimate source for new alleles?
Allele - correct answer Any alternative forms of a gene that produce distinguishable phenotypic effects
Gene pool - correct answer The aggregate of all alleles from one population to another, resulting from the movement of fertile individuals or their gametes
No natural selection, no mutation, no genetic drift, no gene flow, random mating - correct answer What are the conditions of Hardy Weinberg's equation?
Founder effect - correct answer Genetic drift that occurs when a few individuals become isolated from a larger population and form a new population whose gene pool composition is not reflective of that of the original population
Bottleneck effect - correct answer Genetic drift that occurs when the size of a population is reduced by natural disaster or human actions. Typically, the surviving population is no longer genetically representative of the original population.
Relative fitness - correct answer The contribution and individual makes to the gene pool of the next generation, relative due to the contributions of other individuals
Directional, disruptive, stabilizing - correct answer What are the 3 modes of selection
Directional - correct answer Mode of selection where one phenotype is preferred
Disruptive - correct answer Two extreme phenotypes are preferred, but not the middle; mode of selection [Show Less]
