Consider a gene locus with two alleles: A and a. suppose that in a certain population, the frequency of allele A to be p and allele a to be 1-p. Under Hardy-Weinberg's Equilibrium (HWE), the two alleles randomly unite to form three genotypes AA, Aa and aa with probabilities [p,2p(-, a) Suppose we know a population is under HWE, from which n subjects were sampled t0 me their genotypes. The observed frequencies are (ni, n2, ns) of the three genotypes.Form...

The table shows a population consisting of 80 individuals for which genotypes AA, Aa, and aa have been identified and counted. This organism is a diploid, and A and a are the only alleles at the locus. Using the data from this table as a starting point, categorize each statement below as true or false. Genotype Number of individuals АА 40 Aa 30 aa 10 Total 80 The a allele frequency is 1-0.6875 = 0.3125. The number of a alleles...

For a particular gene associated with a degenerative neurological disorder, you surveyed genotype frequencies in a population and found that 16 people had genotype AA, 97 had genotype Aa, 15 had genotype aa. a) Calculate the allele frequencies. b) Calculate the expected genotype frequencies under Hardy-Weinberg Equilibrium. Use the chi-square test to determine whether the observed number of people with different genotypes and expected number of people with different genotypes are significantly different (at an alpha level of 0.05). What...

3. The chi-square test for goodness of fit- No preference Aa Aa A developmental psychologist is studying bonding between healthy newborn bables and immediate family members. He wants to know if mothers use smell to recognize their one-week-old infants. To investigate, he selects a randonm sample of mothers of one-week-old infants. Each mother is presented with a garment worn by her infant and two garments wom by unrelated babies. He asks each of the mothers to identify her infant's garment....
