ASU at the west General Biology 2 (BIO 182) laboratory Hardy Weinberg Problem Set Spring 201 trait is wide ne allele. A forest is sampled; 112 trees with narrow cones and 126 trees with wide cones are counted. Of the narrow cone trees the frequencies 2.4 In a species of pine tree, individuals have either narrow or wide cones. This controlled by genes at a single locus, with the narrow cone allele dominant to the co are 55 are homozygous dominant. What a of the dominant and recessive alleles observed in this sample? 2.5 In humans, individuals may or may not have a widow’s peak. This trait is control by genes at a single locus, with the allele for having a widow’s peak dominant to the allele for not having one. A population of humans is sampled; 41 have a widow’s peak and 59 do not. 12 of the people with a widow’s peak are homozygous dominant. What are the frequencies of the dominant and recessive alleles observed in this sample? 2.6 In a species of corn, individuals have either long or short corn cobs. This trait is controlled by genes at a single locus, with the long cob allele dominant to the short cob allele. A farmer counts 105 long cob and 149 short cob plants in a field. Of the long cob plants, 81 are homozygous dominant. What are the frequencies of the dominant and recessive alleles observed in this sample?
