Two intra-population crosses were done (PA m x PA f) and (ES m x ES f) as homogamic controls, as well as one heterogamic inter-population cross (PA mf x ES mf).
It is estimated as 2 percentages that compare levels of female progeny arising from heterogamic mating versus the homogamic control (Pinto et al.
001, analyses not shown); in fact, in both heterogamic matings between these two populations there was a high fraction of families without offspring in generations 2 and 3 (Table 1).
The lowest values of fertility for heterogamic pairs are those between BC7 and BCA for generations 2 and 3.
