Adiploid cell in a plant undergoes chromosome duplication but fails to divide properly, initiating a tetraploid (4n) branch. this branch produces a 4n flower. what can happen next?
the 4n flower produces 1n (haploid) gametes, which then cross-fertilize with gametes from the original diploid parent species to produce fertile offspring.
the tetraploid (4n) flower produces 2n gametes and may then be able to self-pollinate to produce fertile 4n offspring.
the 4n flower produces 4n (tetraploid) gametes, which then self-fertilize to produce fertile offspring.
the 4n flower produces 2n gametes, which then cross-fertilize with gametes from the original diploid parent species to produce fertile offspring.
