Polygenic sex determination system in zebra fish breeding in Greater Manchester

The primary aim of this study is to find out more about how sex is determined in zebrafish. The most extensively studied mode of genetic SD is chromosomal sex determination CSD as in mammalian and avian species, for example. A strong determinant should produce broods of very similar sex ratio.

BMC Evol Biol. Wide range of sex ratios obtained and two opposite sexes with the same SD genotype both indicate a higher level of complexity than what could be explained by participation of just two loci in the SD process. These data are from experiment 1 and 2 shown in Table S1.

Social-control of sex-change in the bluehead wrasse, Thalassoma-bifasciatum Pisces, Labridae. Impact of daily thermocycles on hatching rhythms, larval performance and sex differentiation of zebrafish.

Hypoxia alters sex hormones, sex ratio and favors a male-dominated population in fish. Identification of markers linked to disease-resistance genes by bulked segregant analysis: a rapid method to detect markers in specific genomic regions by using segregating populations.

Thus, gonad development can be separated into three steps: sex determination, differentiation and maintenance. In contrast to males, however mutant females were able to release mature eggs during normal mating, though the numbers released were significantly lower than wild-type females Crowder et al.

Figure S2 Plots of the number of fish present in each Another environmental factor that is known to have an effect on population over time. The genetic maps were drawn and aligned using Genetic-Mapper v0. Synergistic roles of bone morphogenetic protein 15 and growth differentiation factor 9 in ovarian function.

Developing broodstock resources for farmed marine fish. Rev Fish Sci. Rearing density is another environmental cue known to influence sex ratio of some fish species such as the American eel [90]. Cell , 45 , — A polygenic hypothesis for sex determination in the European sea bass Dicentrarchus labrax.
