In corn snakes, the wild-type color is brown. one autosomal recessive mutation causes the snake to be orange, and another causes the snake to be black. an orange snake was crossed to a black one, and the f1 offspring were all brown. assume that all relevant genes are unlinked. a. indicate what phenotypes and ratios you would expect in the f2 generation of this cross if there is one pigment pathway, with orange and black being different intermediates on the way to brown. b. indicate what phenotypes and ratios you would expect in the f2 generation if orange pigment is a product of one pathway, black pigment is the product of another pathway, and brown is the effect of mixing the two pigments in the skin of the snake.

According to the rna world hypothesis, rna acted as the genetic material and catalyzed reactions in ancient cells. what conclusion can you draw from this? a. this implies that dna and proteins aren't essential in cells today. b. this implies that rna can catalyze any chemical reaction that enzymes catalyze. c. this implies that if a cell has a problem with its dna, its rna can compensate for the damaged dna. d. this implies that dna and proteins evolved after rna.
