Looking at the aquatic food web below, where is energy starting in the food web A. Seagull, penguin, and elephant seal
B. Phytoplankton and seaweed
C. Blue whale and killer whale
D. Crabs, krill, Fish

not the best question format lol but what i think might as scale color is controlled by a single gene with two alleles, the green allele and the yellow allele. when moths that are homozygous for green scales are mated with moths that are homozygous for yellow scales, 100% of the offspring have green scales.

since there are no options posted i'll give you a few examples.

a dolphin's flipper, bird's wing, cat's leg.
