In corn snakes, the wild-type color is brown. Oneautosomal recessive mutation causes the snake to beorange, and another causes the snake to be black. Anorange snake was crossed to a black one, and the F1offspring were all brown. Assume that all relevantgenes are unlinked.a. Indicate what phenotypes and ratios you wouldexpect in the F2 generation of this cross if there isone pigment pathway, with orange and black beingdifferent intermediates on the way to brown.b. Indicate what phenotypes and ratios you wouldexpect in the F2 generation if orange pigment is aproduct of one pathway, black pigment is the product of another pathway, and brown is the effect ofmixing the two pigments in the skin of the snake
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
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
