  1. Genomes are named generically jklm. Therefore, alleles for S (i.e. ABCD) correspond to genomes jklm respectively; and alleles for Z (i.e. 1234) also correspond to genome jklm respectively. α is the probability of double reduction and ranges from 0- 0.14. β is a parameter for chromosome pairing during meiosis and can have values of 0 (disomic) or 1 (tetrasomic). Δ is a parameter that defines which chromosomes show preferential pairing.
