1.) The
self-replicating genetic structures of cells containing
the cellular DNA.
2.) One of a definite number of minute bodies in the cell
nucleus of all plants and animals through which characteristics
are inherited.
Daylily chromosomes
come in sets of eleven. Cells of diploid daylilies
contain 22 chromosomes (two sets). Triploids contain
33 (three sets), and tetraploids contain
44 (four sets). Because the chromosomes in a nucleus
must divide in half to form ova and pollen,
triploids, with an odd number of chromosomes, are usually
sterile. Tetraploids have not been found in species daylilies. |
