Question

A survey was conducted for a certain trait (the ability to roll tongue or inability to roll the tongue) in a population. The result shows that 215 of the respondents can roll their tongue and 85 cannot roll their tongue. The picture below shows a person rolling his tongue. Rolling the tongue into a tube shape is often described as a dominant trait. If the dominant allele is represented by R (can roll tongue) and r represents the recessive allele, calculate the phenotypic frequencies, allele frequencies, the expected numbers of the three genotypic classes and the expected numbers of the two phenotypic classes (assuming random mating). Using chi-square test, determine whether or not this population is in Hardy-Weinberg equilibrium. REMEMBER: Genotype Phenotype HWE term RR and Rr Can roll tongue p2 and 2pq rr Cannot roll tongue q2 Again, follow the format below for your answers. Regarding letter “F” on the format, you will show the computations on how you arrive to the chi-square value and also include the interpretation
