There are mutations that occur in the genes so their DNA is not exactly identical.
Yeah, there can theoretically be a way to determine this.
Yep - and likely enough mutations to be able to differentiate.
Recent research has documented rare cases of paternal mitochondrial DNA (mtDNA) transmission in humans, with studies identifying 17 individuals across multiple families who inherited significant levels of mtDNA from their fathers, ranging from 24% to 76%. This challenges the long-standing belief that mtDNA is exclusively maternally inherited.
Differences in Mitochondrial DNA
Despite sharing the same nuclear DNA, identical twins do not necessarily have identical mitochondrial DNA. Mitochondrial DNA can accumulate mutations during the development of the twins. These mutations can lead to variations in mitochondrial DNA between the twins over time.
“There are mutations that occur in the genes so their DNA is not exactly identical.”
What? No that can’t be right. The Court of Appeals in London are medical experts. I think.
