Meiosis in Solanum phureja [PDF]

Hereditas, 2009
Meiosis and pollen mitosis were studied in a clone of Solanum phureja in order to elucidate the generally high frequency (about 90 %) of tetraploid progeny in tetraploid X diploid crosses involving S. phureja. The first meiotic division was normal with 12 bivalents in metaphase and apparently normal chromosome disjunction.
