Zygosity analysis

Zygosity analysis service

We offer a robust and cost-effective test for determining the zygosity of a twin pair. The test is based on a panel of 47 extensively validated SNPs and the zygosity is calculated as the likelihood of being monozygotic (identical) versus dizygotic (fraternal) given the genotyping data. The genotyping is performed on MassARRAY Platform from Agena (www.agenabio.com). For further information regarding the validation of the SNP panel and zygosity determination see “Large-scale zygosity testing using single nucleotide polymorphisms” by Hannelius et.al:
