Default Re: Genetics question; calculating potential offspring?

From Frederic Bakrys article; "Where the two strategies part ways is in the energy they each invest in generating seeds, as opposed to evaluating hybrids in the field. One admittedly extreme example of the 3x/2x strategy was presented at the 2011 ISHS-ProMusa symposium. The breeders obtained 200 seeds, but only after hand-pollinating 20,000 plants. By contrast, Bakry and his colleagues harvested as many as 500 seeds from a single plant. Their main problem is lack of space to evaluate all the hybrids they could potentially produce. To be sure, not all of them are gems. For example, 6 of the 38 hybrids from a cross between Kunnan 4x and Musa acuminata spp. malaccensis were “non-parthenocarpic plants bearing seedless stunted fruits”. On the other hand, half of the progeny had a bunch weight superior to the one of either parent"
