a population of 1000 individuals, 532 show the dominant phenotype. How many individuals would you expect for each of the three possible genotypes for this trait?17. If 98 out of 200 individuals in a population express the recessive phenotype, A. what percent of the population would you predict would be heterozygotes?
B. Your original population of 200 was hit by a tidal wave and 100 organisms were wiped out, leaving 36 homozygous recessive out of the 100 survivors. If we assume that all individuals were equally likely to be wiped out, how did the tidal wave affect the predicted frequencies of the alleles in the population? C. Is this population in Hardy-Weinberg equilibrium? D. If the allele frequencies did change as the result of the tidal wave, we would say that microevolution has occurred. What do we call the phenomenon that caused this evolution? 18. The gene for albinism is known to be a recessive allele. In Michigan, 9 people in a sample of 10,000 were found to have albino phenotypes. The other 9,991 had skin pigmentation normal for their ethnic group. a. Assuming Hardy-Weinberg equilibrium, what is the allele frequency for the dominant pigmentationallele in this population? b. How many out of the 10,000 people in the sample above were expected to be heterozygous for pigmentation?c. A similar survey was carried out in Wisconsin, but only 2,500 people were surveyed. If allele frequencies are the same in Wisconsin as they are in Michigan, how many people would you expect to have the albino phenotypes in this sample?d. Following are the data that were actually collected in Wisconsin. Perform a chi-square test on these data. Can you accept the hypothesis that the allele frequency is the same in Wisconsin as in Michigan?
