Previous understanding of ZFY gene role as Testes Determining Factor (TDF) has now been strengthened by many experimentations.
The mean read depth ratio of ZFY to ZFX ranged from 0.
Fractional cffDNA concentration estimated by calculating the mean read depth of ZFX and ZFY ranged from 5.
Las exitosas amplificaciones de los segmentos individuales ZFX y ZFY en PCR simples, asi como la deteccion conjunta de ambos segmentos ZFX y ZFY en PCR multiple se detallan en el Cuadro 5.

Este enunciado ha sido sugerido luego del analisis comparativo de los genes ZFX y ZFY bovino, porcino y equino realizada por Poloumienko (2004) y la amplificacion del gen ZF en humanos y diversas especies de animales domesticos y silvestres realizados por Pomp et al.
Several protocols have been established for sexing embryos in farm animals, such as karyotyping (King, 1984), H-Y antigen detection (Andersib, 1987), X-linked enzymatic determination (Monk and Handyside, 1988), and based on the identification of the Y chromosome, such as SRY, ZFY and TSPY genes, include in situ hybridization, Southern dot blotting, polymerase chain reaction (PCR), Loop-Mediated Isothermal Amplification (LAMP) (Miller, 1991; Bredbacka and Peippo, 1992; Gutierrez-Adan et al.
The loci for an EGG comparison were HLCS on chromosome 21 and ZFY (zinc finger protein, Y-linked) on chromosome Y from pregnancies with a male fetus.
Interestingly, we observed the highest detection rate for hCG[beta] mRNA during the first trimester of pregnancy, whereas Lo's group found the lowest detection rate for ZFY mRNA in early pregnancy (8).
1, RT-PCR products corresponding to ZFY mRNA were observed only when male placental total RNA was used in the RT-PCR assay (Fig.
