 Imprinting in the endosperm of angiosperms, a phenomena by which expression of alleles differs depending on whether they originate from the male or female parent, has been shown to explain most failure of interploidy or interspecific crosses in plants. Because of imprinting, seeds develop normally only if a specific dosage is represented in the endosperm, with the relative contributions of genomes in the ratio of two maternal doses to one paternal dose (2m:1p). In Tripsacum, a wild relative of… CONTINUE READING
