Question

According to the Recessive Gene Theory, what controls polyembryony?

Options

• Environmental factors exclusively determine polyembryony

• Polyembryony is a recessive genetic character controlled by multiple genes

• Polyembryony is an always-dominant trait

• Polyembryony is controlled by a single dominant gene

Answer 1

The Recessive Gene Theory, proposed by Kappert in 1933, proposes that polyembryony is a recessive genetic character controlled by multiple genes. Plants carrying certain recessive alleles produce multiple embryos, suggesting a heritable basis for polyembryonic development in angiosperms.
