Cross-species summary: This is a type of XX difference of sexual development (XX DSD) due to variants in the CYP17A1 gene.

Species-specific description: Zhai et al. (2022) report production of all-female (AF) common carp: "Male and female heterozygous cyp17a1-deficient common carp were first obtained using ... (CRISPR/Cas9) technique. An all-male phenotype for homozygous cyp17a1-deficient carp, regardless of the individuals’ sex-determination genotypes (XY or XX), has been observed. A male-specific DNA marker ... was used to screen the neomale carp population with the XX genotype from the cyp17a1-deficient carp. These neomale carp develop a normal testis structure with normal spermatogenesis and sperm capacity. The neomale common carp were then mated with wild-type (WT) females (cyp17a1+/+ XX genotype) using artificial fertilization. All the AF offspring sample fish from the neomale-WT female mating were confirmed as having the cyp17a1+/− XX genotype, and normal development of gonads to ovaries was observed in 100.00% of this group ... . ... The average body weight of cyp17a1+/− XX females was higher ... than that of the control common carp." This study involves genetically modified organisms (GMO).

Genetic engineering: Yes - variants have been created artificially, e.g. by genetic engineering or gene editing
Have human generated variants been created, e.g. through genetic engineering and gene editing
