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

2 The basic hypothesis that we re working with for the formation of BIFs is that during the Hadean and Archean iron Fe accumulated in the oceans until the oceans were saturated with Fe i e the water could hold no more Then when oxygen 0 was introduced the Fe reacted with the O and precipitated until there was no more Fe left in the oceans

1 Most BIFs are banded which indicates episodic precipitation of hematite Make a conjecture about why this pattern exists Hint Remember that the precipitation of hematite depended on oxygen supply What might cause the oxygen supply in the Late Archean Early Proterozoic oceans to fluctuate on a regular basis Where does the oxygen come from What climatic variables might effect this source
