| We conclude that the haploids had a greater frequency of mutant phenotypes than the diploids. |
| The Catipes group has amphimictic diploids and tetraploids and derived from them are all of the polyploid agamic complexes in the genus. |
| Moreover, the high loads of inviable or weak aneuploid pollen produced by triploids induce high selfing rates in normally self-incompatible sexual diploids. |
| Data are presented on the natural occurrence of polyploids, the induction of tetraploids using colchicine and nuclear DNA amounts of diploids and polyploids of both species. |
| At the MAT locus, parental alleles in diploids differ by a heterology of 700 bp. |
| It includes more than 80 wild coffee species, all of which are diploids except C. arabica. |
