| It includes more than 80 wild coffee species, all of which are diploids except C. arabica. |
| At the MAT locus, parental alleles in diploids differ by a heterology of 700 bp. |
| Moreover, the high loads of inviable or weak aneuploid pollen produced by triploids induce high selfing rates in normally self-incompatible sexual diploids. |
| The construction of maps of autotetraploids is a much greater problem than that of maps of allogamous diploids. |
| Previous work has calculated the covariance expected under autosomal inheritance in diploids and haploids. |
| Following selection, haploids produce gametes mitotically and diploids produce gametes meiotically that then enter the random mating pool. |
