Answer :
By examining whether the mother possesses a mutant gene that prevents her from being able to save her embryo when the father contributes a wild-type gene, maternal-effect genes have been identified. Even before the egg has been fertilized, maternal influence genes have an impact on the embryo's basic structure.
What traits define a genetic maternal effect?
People don't exhibit the phenotypes that go along with their own genotypes. Male progeny exhibit father-like genotypes, whereas female progeny exhibit mother-like genotypes. The phenotypes linked to their own genotypes are displayed in progeny.
In genetics, maternal effects happen when an organism exhibits the phenotype predicted by the mother's genotype, regardless of its own genotype. This is frequently because the mother provides messenger RNA or proteins to the egg.
