A grower has one spider plant with a desirable combination of alleles. This plant forms plantlets on arching stems and can also produce seeds after fertilisation with another spider plant. The growing conditions will remain favourable.
Which choice will produce new plants with the selected combination of alleles?
root the plantlets, because meiosis produces genetically identical diploid cells for their growth
root the plantlets, because mitosis copies every chromosome exactly into their cells
use the seeds, because restoring the diploid chromosome number also restores the selected plant's genotype
use the seeds, because each gamete contains a complete copy of the selected plant's DNA
