Molecular/structural orientations (gradients) in an egg are thought to play a significant role in development. What evidence indicates that the maternal genotype is involved in providing such gradients?
A) Snail shell's coil based on environmental conditions. B) Results (non-Mendelian) indicate that the direction of shell coiling in snails is determined by the genotype of the mother, not the genotype of the zygote. C) Results indicate that the snail shell coiling is passed exclusively from the mother. D) The snail's father's genotype dictates the next generation's phenotype. E) The snail shell coiling depends on the genotype of the mother and the offspring.
