Discrete trait correct answers *Inherited trait* that exhibits *distinct phenotypes* Quantitative traits correct answers A trait that exhibits *continuous phenotypic variation* Asexual reproduction correct answers *Reproduction* where offspring inherit DNA from only *one parent* E.g. binary fission, budding and parthenogenesis Sexual reproduction correct answers Any form of reproduction in which *genes* from *two parents* are combined via *fusion of gametes*, producing offspring that a...

What is the difference between a categorical and continuous variable? correct answers Categorical are assigned to discrete categories; continuous can take any value in a range. What is the difference between an explanatory (or independent) variable and a response (or dependent) variable? correct answers Explanatory is the factor that varies in an experiment; response is measured as the explanatory variable varies. In describing a dataset, what does the mean represent? correct answers (Usua...

Pure lines are homozygous for the gene under study. hybrid correct answers the offspring of parents from two different strains, populations, or species parental generation correct answers the adults used in the first experimental cross of a breeding environment F1 generation correct answers first filial generation. The first generation of offs...
