Summary

We chronicle the development of eggs stripped from a wild caught hybridPhoxinus eos x Phoxinus neogaeus, that were then mixed with sperm formPhoxinus eos. Approximately half the eggs died in development. It is hypothesized the dead embryos are the male sex, the postulated heterogametic sex. Egg hatching time approximated that ofneogaeus instead ofeos. Possibly this is a maternal effect, reflecting the maternal ancestor of the hybrid. Several laboratory hybrids were karyotyped and all had triploid cells. The laboratory hybrids were also heterozygous at both diagnostic allozyme loci examined.
