Re: I. sibirica X I. pseudacorus

 

I am interested in knowing what happens when you cross the amphidiploid SDB with a TB and get an IB?

Example 2: SDB's are amphidiploids that combine the tetraploid chromosomes of MDB's (32) from pure I. pumila backgrounds and the 48 chromosomes of the TB's.  Each gamete will get one set of two sets chromosomes and two sets of twelve for a total of 40 chromosomes. When these plants form gametes the chromosomes divide the set of 16 I. pumila chromosomes into two sets of 8 and divide the 24 TB chromosomes into two sets of twelve. The set of 8 chromosomes pair up and the set of twelve pair up. The cell divides and each gamete will have one set of eight and one set of twelve for a total of 20 chromosomes.
