Sex and meiosis in autotetraploid
Pacific oyster, Crassostrea gigas (Thunberg).
Because an autotetraploid
can theoretically carry four alleles per locus, the number of combinations within a gene and in epistatic interactions among genes is much higher than can be achieved in diploids.
Tetraploid cultivated potatoes are believed to be autotetraploid
with a chromosome base number of 12 and a genome size estimated at 840 million base pairs.
If the same meiotic pattern is shown in more than two of the hybrids with diploids having different genomic constitutions, the polyploid plant is an autotetraploid
derivative could move to complete metacentricity, but only by fusions between homologues producing when homozygous a pair of pseudoisochromosomes.
