Interfamilial characterization of a region of the ZFX and ZFY genes facilitates sex determination in cetaceans and other mammals.
Sequence polymorphism of homologues ZFX and ZFY, in a 604-base pair exon region, was examined in 10 known males and 10 known females across seven cetacean families and used to design a simple, highly sensitive and widely applicable fluorescent 5' exonuclease assay for gender determination in cetaceans. Multiplex amplification, cloning, and sequencing of these previously uncharacterized regions ...
متن کاملEvolution of the Zfx and Zfy genes: rates and interdependence between the genes.
A phylogenetic analysis of sex-chromosomal zinc-finger genes (Zfx and Zfy) indicates that the genes have not evolved completely independently since their initial separation. The sequence similarities suggest gene conversion in the last exon between the duplicated Y-chromosomal genes Zfy-1 and Zfy-2 in the mouse. There are also indications of conversion (or recombination) between the X- and Y-ch...
متن کاملCpG islands in human ZFX and ZFY and mouse Zfx genes: sequence similarities and methylation differences.
The human ZFX, human ZFY, and mouse Zfx genes have CpG islands near their 5; ends. These islands are typical in that they span about 1.5 kb, contain transcription initiation sites, and encompass some 5' untranslated exons and introns. However, comparitive nucleotide sequencing of these human and mouse islands provided evidence of evolutionary conservation to a degree unprecedented among mammali...
متن کاملA Genetic Method for Sex Identification of Raccoons (Procyon lotor) with Using the ZFX and ZFY Genes
A genetic method for sex determination in raccoons was developed based on nucleotide differences of the zinc finger protein genes ZFX and ZFY. Four novel internal primers specific for ZFX or ZFY were designed. PCR amplification using two primer sets followed by agarose gel electrophoresis enabled sex determination. 141-bp and 447-bp bands were in both sex, and 346-bp band was specific only in m...
متن کاملComparison of human ZFY and ZFX transcripts.
ZFY is a candidate for the primary sex-determining gene (TDF, testis-determining factor) on the human Y chromosome. We have isolated cDNA clones of ZFY and its homologue on the X chromosome, ZFX. The transcripts of these genes are very similar to each other and encode predicted proteins of equal size. The conceptual amino acid sequence of both proteins contains an acidic domain, similar to the ...
