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)Results indicate that the snail shell coiling is passed exclusively from the mother.
B)The snail shell coiling depends on the genotype of the mother and the offspring.
C)The snail's father's genotype dictates the next generation's phenotype.
D)Snail shell's coil based on environmental conditions.
E)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.

Question

The evidence that the maternal genotype is involved in providing molecular/structural orientation gradients in eggs is that non-Mendelian results indicate that the direction of shell coiling in snails is determined by the genotype of the mother, not the genotype of the zygote. This suggests that the mother is providing some kind of molecular or structural gradient in the egg that influences the development of the offspring.
