PSYC 2606 Study Guide - Midterm Guide: Disruptive Selection, Genetic Drift, Heterozygote Advantage
Document Summary
Mcdb 2150 practice test 4: below is shown a complementation table from neurospora mutants that cannot make the amino acid tryptophan. Given this information, how many genes are involved in the synthesis of tryptophan: 1, 2, 3, 4, 5, you have the seeds from inbred tomato plants and seeds from genetically diverse tomatoes. You grow both types of seeds in the same greenhouse, measure the stem lengths and plot distribution curves as shown to the right. The total variance in this distribution curve is due to genetic variance (vg) and environmental variance (ve). You find several additional mutant fly lines with lethal patterning defects, which you maintain as heterozygotes. You suspect that at least one of the mutant lines is the result of a mutation in a maternal effect gene, while the other is the result of a mutation in a hox gene.
