What is the first variable that can be calculated given these data, and what is the final variable we are requesting you to calculate? "In Finland, 256 people out of 10,000 are homozygous for the CCR5 allele mutation resulting in HIV resistance. Assuming the locus is in Hardy-Weinberg equilibrium, what is the expected genotype frequency of heterozygous carriers for the CCR5 mutation?"

QTL mapping and GWA (association) mapping are two different methods used to identify genes that affect complex traits. For each of the following statements, choosewhether it applies to QTL mapping, association mapping, or both.whether it applies to QTL mapping, association mapping, or both.

In a certain population in the US, the frequency of CCR5-Δ32 homozygous individuals is 1%. Assuming genetic equilibrium, what is the frequency of heterozygotes in this population?

Snow geese (Chen caerulescens) come in two color types, white “snows” and “blues” with dark bodies. A single gene controls coloration, where the dark (“blue”) allele (D) is dominant. Researchers using genetic testing are able to determine the following numbers of individuals of each genotype in another population of geese: DD = 10576, Dd = 14503, dd = 4922. -According to the Hardy-Weinberg equilibrium, what is the expected number of individuals of genotype DD? -Calculate the chi-square statistic from these data. What is the value of the chi-square statistic?

Pretend that you are comparing the actual genotype distribution for a population with the distribution of genotypes predicted by the Hardy-Weinberg theorem.  So your hypothesis is that the population is in Hardy-Weinberg equilibrium (i.e. that actual population data fit the Hardy-Weinberg expectations).  If you carry out a chisquare goodness of fit test and calculate a total chisquare value of 0.03 with 1 degree of freedom (see table), what does this mean? (select all true statements)a) The data do NOT fit the hypothesized distribution.b) The data do fit the hypothesized distribution well enough, so we accept the hypothesis at this time (i.e. we cannot reject the hypothesis). c) The probability that the data came from a population in Hardy-Weinberg equilibrium is too small, so we reject the hypothesis.d) The probability that the data came from a population in Hardy-Weinberg equilibrium is too big, so we reject the hypothesis.e) The data support Hardy-Weinberg expectations – there is no…
