Question
Dr. Van Nostrand is a researcher in a lab that studies nutria (a large aquatic rodent). He has identified three genes in the nutria genome that all reside on the same chromosome. In nutria, Tufted tails (7) are dominant to non-tufted tails (t), brown coat color (B) is dominant to white coat color (b) and long whiskers (L) are dominant to short whiskers (/). To map these genes relative to each other, he mated tufted tail (7), brown coated (B), long whiskered (L) nutria that were heterozygous for all three traits with non-tufted tail (t), white coated (b), short whiskered (1) nutria that were homozygous for all three traits (i.e. he performed a test cross). The following numbers and types of offspring were obtained from this cross: Phenotype Tufted, brown coated, short whiskers (T, B. I) Non-tufted, white coated, long whiskers (t, b, L) Non-tufted, brown coated, short whiskers (t, B, I) Tufted, white coated, long whiskers (T, b, L) Tufted, white coated, short whiskers (T,b,I) Number 500 550 151 149 195 Non-tufted, brown coated, long whiskers (t, B, L) 200 Tufted, brown coated, long whiskers (T, B, L) 26 26 Non-tufted, white coated, short whiskers (t, b, I) 29 29 Total 1800
