A maternal effect is a situation where the phenotype of an organism is determined not only by the environment it experiences and its genotype, but also by the environment and genotype of its mother. In genetics, maternal effects occur when an organism shows the phenotype expected from the … See more In genetics, a maternal effect occurs when the phenotype of an organism is determined by the genotype of its mother.
