Shell coiling in some snails has been found to be determined by the genotype of the snail's mother, rather than its own genotype

baherus [9]

Answer:

maternal effects

Explanation:

<em>The correct answer would be maternal effects.</em>

<u>The maternal effect is a genetic phenomenon that is characterized by an organism having the phenotypic expression that is compatible with the genotype of its mother irrespective of the organism's genotype itself.</u>

This condition often occurs as a result of the mother supplying messenger RNA or protein to the egg that results in the formation of a zygote/embryo. Consequently, the genome of the mother dictates the functionality of the molecule in such offspring.
