Amplification of the Zfy and Zfx Genes for Sex Identification in Humans, Cattle, Sheep and Goats

Aasen, Eric, Medrano, Juan Fernando·1990·Nature Biotechnology

Abstract

We describe a quick and efficient method of determining the sex of DNA samples from humans, cattle, sheep, and goats. Using universal primers we have amplified 447 or 445 bp fragments from male or female genomic DNA corresponding to the ZFY or ZFX genes. Restriction fragment length polymorphism (RFLP) analysis of the fragments yielded specific banding patterns between the two sexes in these species. Horse, pig and rainbow trout fragments did not show RFLPs with the group of enzymes chosen for the other species. Use of this method would allow animal breeders to determine the sex of preimplantation embryos before transfer to recipient females. Human embryos at risk for sex-linked disorders could be sexed soon after in vitro fertilization (IVF) and options considered before implantation.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
