The genetic map shows the location of three genes on a chromosome. Order the gene pairs based on their likelihood of recombining from most likely to least likely to recombine. A B с genes A and B genes B and C Most likely Least likely Answer Bank genes A and C

36 Linked genes are NOT assorted independently. Select an answer and submit. For keyboard navigation, use the up/down arrow keys to select an answer. a TRUE b FALSE

If two genes are unlinked the recombination frequency will be?     25%     50%     75%     100%

A research team interested in mapping human genes discovered a new restriction length polymorphism (RFLP). The nature of the polymorphism is shown in the figure below.  a) They test the RFLP in a family with the pedigree below. The individuals colored blue are affected by hemophilia, a blood-clotting disease. On what chromosome is the RFLP found?

You are a developmental geneticist studying flowering time variation in Arabidopsis. You perform a mutagenesis screen to identify mutants in the photoperiod pathway. You conduct the screen and find two different plants that show the same mutant phenotype. You then use a complementation test. What is the predicted outcome of this test if both phenotypes are caused by mutations in separate genes? recover the wild type phenotype overexpress the gene O recover the mutant phenotype

A pair of paralogous repeats, A and B, have 96% sequence similarity and therefore can promote non-allelic homologous recombination (NAHR). They exist in four possible arrangements in a genome, illustrated below as arrangements 1 – 4. What is the result of NAHR between repeats A and B in arrangement 1? A.Translocation between chromosomes 1 and 2 resulting in monocentric chromosomes B.Deletion or duplication of the region between A and B C.Translocation between chromosomes 1 and 2 resulting in acentric and dicentric chromosomes D.Inversion of the region between A and B
