WebMar 15, 2024 · Out of 86 gynogenetic embryos, 85 developed as females (one embryo hatched but died as a young larva). By contrast, 30 out of 31 amphimictic embryos developed as males (one also died as a young larva) . We confirmed that only males are the result of a true fertilization using single-nucleotide polymorphism (SNP) genotyping. WebViable gynogenetic diploids can be induced by activation of eggs with UV-irradiated spermatozoa and subsequent diploidization of the maternal chromosome set, by inhibiting either the second polar body extrusion or the first cleavage (Fig. 1). The former type of gynogenetic diploid (gynogen) is termed “meiotic gynogenetic diploid,” “polar ...
