Answer 1

maternal effects

Step-by-step explanation:

The correct answer would be maternal effects.

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.

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.
