Dorothy, as I understand it, if both parents are tets, then the resulting
progeny are considered to be tets. However, as I understand it, not all
bearded tets are the same. SDBs have different numbers of chromosomes than
TBs, the way it was explained to me. It was further explained that for a
cultivar to be fully fertile, each chromosome must match up with another; no
chromosomes (or whatever the sex cells are called that pair up with each
other) left over without a mate or reduced or nil fertility. I therefore
wonder about a tetraploid MTB that is from SDB, IB, and TB breeding.
