Are You Genetically More Like Your Mother or Your Father?

Thursday, January 26, 2017. Author Dr Pleuni Hooijman and Dr Nathan West

Every gene report in the FitnessGenes 'Genetic Results' section is represented by two letters (e.g. RR, RX or XX for the ACTN3 gene result), each representing a variant or variation at a specific region within a given gene, also termed an ‘allele’. The reason why you have two alleles for each gene result, is that you inherited one from each of your biological parents. However, does this mean that we receive exactly half of our DNA from our father and half from our mother?

Well, no. We all actually receive more DNA from our biological mothers, albeit the differences are extremely small. Does this surprise you? And how can this be the case? It comes down to the source and type of DNA.
