Bio280 Exam 2 Questions And Answers!!

A new fossil of a mammal is discovered from Eocene deposits that is remarkable for its extremely short neck coupled with very long legs. What would you predict for the number of neck vertebrae that would be found in this fossil? - 7 Alleles are most likely to show linkage disequilibrium if they: - occur very close together on the same chromosome An approach to estimating the narrow-sense heritability of a trait - measure the trait in parents and their offspring for comparison Based on the graphs below, which trait in C. elegans shows a genotype x environment response? - Fertility Based on the results of the observations of the R. Lenski lab on E. coli, which of the following evolutionary processes has been documented to occur experimentally - all of the following: mutation, selection, genotypic change, phenotypic change Detailed genetic studies found evidence of a selective sweep for a candidate domestication gene in sunflower that affects which activity? - seed dormancy F statistics developed by Sewall Wright are based on: - relative levels of heterozygosity Genes that affect this disease have been the focus of Genome-Wide association mapping studies because the disease is the leading cause of human mortality in the U.S.: - coronary heart disease Genes that control functional traits related to adaptation to the environment in two different ecotypes of Mimulus guttatus are retained together because of what type of genetic change? - inversion
