Because of the labor required to estimate the relative fre- quency of F 1 individuals in the progeny ofmixed pollinations, we studied the progeny of each cross type from eight of the 17 seed ... 62% of crosses between congeneric species showed no clear reduction in F 1 fitness. Furthermore, they found that the time span of the loss of hybrid fertility and viability is often longer than the...
