The resultant hybrid, of the number is doubled, immediately behaves like a diploid because of the reappearance of the homology lost in the diploid hybrid state. This chromosome number would be twice the number of the two alleged parental taxa. My initial work indicated this was not the case. I did see some meiotic irregularities in A. blakei, however, and this is always a possible indication of hybrid origins. Mixing genetic material from two different species is often disruptive when gametes form.
Sexual sterility is more common among hybrids as opposed to more stable parental species.
This was the case with A. blakei . I was further interested in the chemical markers that might show some hybrid origins in these taxa. This chemical approach is clearly a good way to examine the origins of species and their relationships. During that time much attention was focused on proteins. However, plants have a variety of chemicals that are unique.
