BIO320 – SPRING 2010 FINAL FORM CODE 0 (BLUE) 1. In the Hfr X F- cross shown below, the pyr + gene from the Hfr strain enters the recipient cells five minutes after the cells are mixed together to allow mating. At this time, no met+, xyl+, tyr+, arg+, his+ or mal+ recombinants are observed. Hfr pyr + met + xyl + tyr + arg + his + mal + x F pyr met xyl tyr arg his mal (NO ORDER IS IMPLIED) The mating is allowed to proceed for 30 minutes and then pyr + recombinants are selected on the appropriate medium. The pyr + recombinants are then screened for the presence of other markers donated from the Hfr strain. These markers are observed in the following frequencies: Per cent of pyr + colonies met + 32 xyl + 94 tyr + 7 arg + 59 his + 0 mal + 71 What is the order of the genes? A. origin- xyl-mal-arg-met-tyr-his-pyr B. origin- pyr-his-tyr-met-arg-mal xyl C. origin- pyr-xyl-mal-arg-met-tyr-his D. origin- pyr-met-xyl-tyr-arg-his-mal E. origin- his-tyr-met-arg-mal xyl-pyr 2. Genomic imprinting - expression of only one allele of certain autosomal genes - is observed in mammals and in flowering plants. This is thought to be because: A. In both mammals and flowering plants, a developing embryo with genes from both parents draws resources from the female parent only, causing a conflict of the parents’ genetic interests. B. Mammals and flowering plants inherit imprinted genes from only one parent.
