Polysomic segregation, temperature sensitivity, a range of genetic expression levels, and a high potential for genetic polymorphisms combine to create a relatively high level of phenotypic instability for the nonflowering trait.

The statistical association between Cep17 copy number, categorized as polysomic or eusomic, and ER, PgR, and Ki-67 expression, age, lymph node status, and histologic grade was assessed by using the x2 test.
(54) Patients with chromosome 17 polysomic breast cancer in the absence of HER2 amplification or 3+ IHC are not candidates for targeted therapy, and they have not been considered eligible for adjuvant trastuzumab trials or trials comparing different HER2 therapies.
The commonly grown form of smooth bromegrass is a polysomic octoploid, 2n = 8x = 56, with a genome structure of AAAA[B.sub.1][B.sub.1][B.sub.2][B.sub.2] (Ghosh and Knowles, 1964; Armstrong, 1980, 1992).
These observations seem to indicate that either both tetraploids and octaploids are disomic polyploids or that they are polysomic polyploids under strong selection for bivalent pairing.
Use of haploids and isozyme markers for genetic analysis in the polysomic polyploid potato.
Of the species listed, none is a diploid, and most are characterized by polysomic inheritance.
