If 6 distinct loci contribute equally to a single trait and each locus has 2 distinct alleles (one completely dominant and one recessive), how many different phenotypes (assuming only a genetic component to phenotypic variation)? How many distinct genotypes? What are the assumptions of the Hardy-Weinberg law regarding the effect of reproduction on allelic frequencies in a population? A correlation coefficient (r) of 0.1 indicates a _____and _____relationship between two different phenotypic traits x and y. The locus encoding the enzyme peroxidase in ponderosa pine trees growing at Glacier Lake, Colorado has two alleles. R^2 and R^3. If the frequency of the R^2 allele is 0.4 and the frequency of the R^3 allele is 0.2 and the two alleles are in Hardy-Weinberg equilibrium, what is the expected frequency of heterozygous R^2R^3 pine trees: In a yin-yang fashion, the number of new alleles introduced by mutation is constantly balanced by the elimination of alleles through _____ If a trait exhibits a normal distribution, _____percent of the individuals in this population fall within 1 standard deviation units of the mean, _____within 2 standard deviations of the mean, _____and within 3 deviation units of the mean, standard deviations of the mean.
