QUESTION 12 Patrick was hired by Dr. Ryan to work on a maize genome project. His research assignment was to map three linked genes which can cause brown midrib ( bm), virescent seedling (V) and purple aleurone (pr) phenotypes respectively in maize. All the above mentioned alleles are recessive ones compared with the dominant wild type phenotype (designated with+). Dr. Ryan gave Patrick a triple heterozygote strain which has both the recessive mutant and dominant wild type alleles. Patrick was asked to testcross the strain and collect the data from the progeny. Here is the data Patrick obtained after one year's hard work in the field. Based on the phenotype, they are categorized into eight groups in the following talble (1-8 below). Please answer the Multiple Answer Questions below. (1) Phenotypes brown midrib (2) virescent seedling, purple aleurone (3) Wild type Number of Progeny 710 698 170 150 42 (4) brown midrib, virescent seedling purple aleurone (5) virescent seedling (6) brown midrib, purple aleurone (7) purple aleurone (8) brown midrib, virescent seedling 38 53 Question #12: what is the distance between pr and bm genes? a. 4.84cm b. 18.04cm c. 22.88cm Percentage
