  • Description: <p>Information from 17 interspecific hybrid combinations is now available. The thicker jelly of the eggs of some species may prevent or retard fertilization by sperm of other species. Genetic compatibility ranges from uniform failure at blastula to nearly normal viability and fertility in the F<sub>1</sub>and backcross generations. There is no obvious correlation of the levels of genetic compatibility and the presently assigned levels of taxonomic distinctness.</p>
