Plant In the appropriate box fill in the two possible phenotypes each poulble genotype and what you expect to observe on a gel when testing that genotype In the larger boxes explain how your thinking that led you to answer the way that you did Genotype Phenotype Genotype Genotype Phenotype I think this because I think this because I think this because Expected Result Expected Result Expected Result I think this because I think this because I think this because

Sample Phenotype Possible genotype s 1 2 3 4 On the Image of a gel to the right draw in your expected results In some cases you cannot predict whether a particular band will be present or absent on your gel If it is uncertain if a certain band will be present draw it as a dotted line For each lane explain why you predict the results that you drew Lane 1 Ladder Lane 2 1 000 900 800 700 600 500 400 Lane 3 300 200 100

3 In organisms used for genetics quite anthocyaninless reflect the mutant phenotype while names like DFR refer to the protein the gene produces Why not Just have one name 4 If phenotypes are caused by genotypes can you explain why the genotypic and phenotypic ratios for Mendelian traits are different How is it that a 3 1 phenotypic ratio can be caused by a 1 2 1 genotypic ratio 5 This lab demonstrates how the anthocyaninless gene affects stem color in Brassica rapa Think of another trait you are familiar with for example human height In what ways do you think anthocyaninless is a good model for studying the inheritance of phenotypes In what ways may it not be the best model
