- a two different alleles, having two different alleles for a trait
- b in eukaryotic cells, a process of cell division that forms two new nuclei, each of which has the same number of chromosomes, asexual
- c process by which descendants of ancestral organisms spread into various habitats and accumulate adaptations to diverse ways of life
- d A class of common sex-linked human disorders involving several genes on the X chromosome; characterized by a malfunction of light-sensitive cells in the eyes; affects mostly males but also homozygous females
- e Genetic drift that occurs when the size of a population is reduced, as by a natural disaster or human actions. Typically, the surviving population is no longer genetically representative of the original population.
5 Multiple choice questions
- Genetic drift that occurs when a few individuals become isolated from a larger population, with the result that the new population's gene pool is not reflective of the original population.
- A definition of species in terms of ecological niche, the sum of how members of the species interact with the nonliving and living parts of their environment.
- A genetic condition of having three chromosomes instead of two. The conidtion causes various birth defects
- more individual are produced then can survive and reproduce. there is variation of characteristics within a population. there is unequal reproductive success based on variation, limited resources, comptition for resources, passing down traits to offspring, variation within a population
- the number of off spring an individual has compared to others in the population
5 True/False questions
Darwin conclusion → more individual are produced then can survive and reproduce. there is variation of characteristics within a population. there is unequal reproductive success based on variation, limited resources, comptition for resources, passing down traits to offspring, variation within a population
phenotype → physical traits of the organism, what an organism looks like as a consequence of its genotype
gene flow → combined genetic information of all the members of a particular population
antigens → Random errors in gene replication that lead to a change in the sequence of nucleotides; the source of all genetic diversity, changes in genetic material
biological species concept → defines a species as a set of organisms with a unique genetic history
