varegiation is a result of different cytosplasmic dna in embryonic cells that then replicate and differentiate, producing areas of different color. Chloroplasts and mitochondria and other organelles thought to have originated through endosymbiosis would be where the extranuclear (cytoplasmic) dna is coming from/housed. Thus, momma oocyte could have regular chloroplasts but if pollen contributes some chloroplasts that dont make the green pigment as well (which is super not common but can happen), then a fertilized embryo could end up with different chloroplast dna and thus (cellular) phenotype throughout the plant
