January 7, 2019: How sex is determined in frogs is complicated. In some species, males have two different sex chromosomes (an XX-XY sex chromosome system, like mammals) whereas females of other species are the sex with two different sex chromosomes (a ZZ-ZW sex chromosome system, like birds). Whether a species has an XX-XY or ZZ-ZW system has changed dozens of times throughout frog evolution. The Japanese wrinkled frog (Glandirana rugosa) is an evolutionary witness to the remarkable complexity of frog sex determination. Some populations have an XX-XY sex chromosome system whereas others have a ZZ-ZW system. In central Japan, there are adjacent populations of wrinkled frogs with different sex chromosome systems. Ogata et al. (2018) recently discovered a hybrid zone where these two populations meet. They found here a ZZ-ZW system but also a hybrid sex chromosome system. In this hybrid population, the Z-chromosome is partially derived from the old ZZ-ZW population’s Z-chromosome and partially derived from the XX-XY population’s Y-chromosome. The hybrid population’s W-chromosome is surprisingly derived from the X-chromosome of the XX-XY population. This work illustrates how the fantastic diversity of sex determining systems in frogs can arise from recycling sex-determining genomic material across populations and species (Written by Max Lambert).
