Re: Polyploid test

Which plants were triploid and tetraploid?

What is ploidychimera A?

Could someone please refresh my memory on how ploidy affects pollination, among ploidy variation? (f. ex. crossing a diploid and a diploid or a diploid and triploid, would you get seed from each cross, higher numbers of seeds for same ploidy v. different ploidy, or are any sterile due to ploidy?)

investigated 11 plants Four, including Slick Willy and Blue Mouse
Ear, turned out to be diploid, two were triploid, two were tetraploid,
and two were ploidychimera A very high score of polyploids from
only 11 plants. In case any of you is interested and thinks he has
plants that might be polyploids one way or another, why not send
me one to check ?
