BIOL 351 Lecture Notes - Lecture 11: Bumblebee, Anthocyanin, Mimulus
Document Summary
The endless forms, genetics, development and evolution of floral trait. Only few can do this, study of ecology of organisms. When you take carotenoids away from cardinalis, the red flower becomes yellow. Both anthocyanin and carotenoid content are important for pollinator preference. Both anthocyanin and carotenoid content variation are controlled by a few major loci. 1 major locus responsible for each of the traits this causes a problem for identifying the gene for the differences in anth. Use near-isogenic lines (nils) for fine mapping if you mix both types, the f1 serial backcrosses to lewisii (nil) knock down in the genotype produce phenotype that we presumed . Change the phen to dark to light pink. Put some length into isogenic compound, and nothing was produced because that was the recessive allele. Mutation that caused the phenotype why do they change aa? (short protein) the difference is that one is acidic. If you aligh homologs from other species it is conserved.
