Once fertilization and karyogamy occur, ig1 would allow for embryogenesis to take place in the unicellular zygote.
Unidirectional incompatibility caused by this bacterium occurs when infected males mate with non-infected females, making the eggs die from failure in chromatin condensation, as a product of incomplete karyogamy (Noda 1984, Boyle et al.
Twenty-two percent of the variation in fertilizing sperm length was associated with historical events perhaps due to constraints imposed by the requirements for successful sperm storage by females, penetration of the micropyle, and subsequent karyogamy. As nonfertilizing sperm are not under the same selection pressures of fertilizing sperm, the evolution of short sperm may be decoupled from requirements of reproduction.
