Origin of S. pastorianus group 1 and group 2 strains based on two theories. (A) hybridization between diploid S. cerevisiae and S. eubayanus followed by chromosomal deletions in the S. cerevisiae sub- genome of group 1 strains. (B) The hybridization of a haploid S. cerevisiae and a diploid S. eubayanus lead to a triploid hybrids (3n) followed by a second hybridization event in group 2 strains (4n) (Figure adapted from Okuno et al. (2016).
