For flowering plants, can flow cytometry of seed from muti-generational interaction of two species and their offspring help us decide if wide differences in genome size for the two species and their offspring is a function of differences in chromosome count versus chromosome length?
Flow cytometry of seed allows us to examine the contributions by the 2 parents to the resulting offspring from generation to generation.
The basic premise is flow cytometry scores for the offspring of "triploid" intermediates would distribute differently if the issue was length versus count. Fine distribution would indicate "aneuploids" because of counts whereas wide distribution would indicate length because length differences are concentrated in only a few chromosomes.
This basic premise proved faulty since flow cytometry scores indicate fine distribution (genome size scores reflecting every potential aneuploid between triploid and tetraploid) but documented chromosome counts indicate the issue is length.
What are the normal distribution patterns in terms of genome size for multigenerational offspring between 2 species having wide differences in chromosome length?
