What is DNA sexing?

DNA sexing is nowaday the best method to determine the sex of the birds. Therefore, Genimal Biotechnologies gives the opportunity to bird breeder to determine the sex of their birds with accuracy and short delay.

Nøyaktighet

Forsinkelse

Arter

We can do DNA sexing on all bird species. However we cannot sexed ratites (Ostrich, Rhea, Emu) and some glossy starling.

flere sende

Order a pack of DNA sexing now and then send your samples at different times within the limit of 2 years. For example, you can send 2 samples tomorrow, 3 other in two months etc.

1 day result

Possibility to get the result in 1 day with alternativet express

Metode for analyse

As in humans and most animals, the sex of birds is determined by two chromosomes called “sex chromosomes”. In birds, males have two identical sex chromosomes named ZZ. However, in females, these two chromosomes are different and named ZW. Indeed, the Z chromosome is therefore present in both sexes while the W chromosome is only present in females. The method of DNA sexing realized at the laboratory Genimal Biotechnologies consists of detecting a particular gene that, although found on both chromosomes, is smaller in size on the W chromosome than on the Z.

DNA utvinning

DNA i sex kromosomer er isolert fra den sample cells (feather cells, blood cells, etc.).

DNA multiplikasjon

Et stykke DNA brukes for DNA sexing er multiplisert millioner ganger å gjøre det synlig.

Oppdagelsen av genet

DNA is now detectable with a specific machine because it is present in billions of copy. In females (ZW), two bands of DNA are observed. The first band corresponds to versjonen av store genet på Z-kromosom og andre bandet tilsvarer the version of the small gene on the W chromosome. In males (ZZ), only one band is observed because both chromosomes are on the same size (Z).
