Normal plant development requires epigenetic regulation to enforce changes in developmental fate. Genomic imprinting is a type of epigenetic regulation in wh...

Genomic imprinting, the allele-specific expression of a gene dependent on its parent-of-origin, has independently evolved in flowering plants and mammals. In mammals and flowering plants, imprinting occurs in the embryo as well as in embryo-nourishing tissues, the placenta and the endosperm...

Imprinted gene expression--the biased expression of alleles dependent on their parent of origin--is an important type of epigenetic gene regulation in flowering plants and mammals. In plants, genes are imprinted primarily in the endosperm, the triploid placenta-like tissue that surrounds and...

Mom is what?
The seed's shape, size, and color are based solely on the mother. Different pollen won't change that. However the genetics contained within that seed depend on both parents. Some traits will only be passed on by the seedbearing plant, and some will only be passed by the pollen donor. And the other side of the coin, some traits will not be passed on by either parents. And this changes when the position of the parents changes.
