Question
1.) If 5 distinct loci contribute equally to a single trait and each locus has 2 distinct alleles how many different genotypes exist for this trait ?2.) The locus encoding the enzyme peroxidase in ponderosa pine trees growing at Glacier Lake, Colorado has 2 alleles, the wild type allele R squared and recessive allele R cube. If the frequency of the R squared allele is 0.4 and the frequency of the R cube allele is 0.6, and the 2 alleles are in Hardy Weinberg equilibrium, what is the expected frequency of heterozygous R squared R cube pine trees? A) 0.09 B.) 0.21 C.) 0.42 D.) 0.49 E.) 0.90
3. In a population confirming to the Hardy Weinberg law, if the frequency of homozygous recessive mutant individuals for a given trait is 0.09, what is the frequency of the wild type allele for this trait? A.) .91 B. Square root of .91 C.) square root of 0.7 D.) 0.7 E.) not enough information to determine
4. An correlation coefficient of 0.05 for amount of coffee drank daily and incidence of cancer of observed in humans means that drinking lots of coffee protects against cancer. A. TRUE B. FALSE
5. Hardy Weinberg equilibrium leads to fixation of the wild type and mutant recessive alleles in a 50:50 ratio in a population. A. TRUE B. FALSE

Explanation / Answer
1).
It is given that, the number of distinct loci is, 5; and each locus contains two alleles. The formula for calculating the number of possible genotypes is,
(X2n + Xn)/ 2
Where, n = number of loci = 5
X = Number of alleles per locus = 2
Thus, the number of possible genotypes is = 2^10 + 2^5 / 2 = 528
