mutations

Hello, I just came across this very old but interesting article. It is a study done by the University of Oxford, and it demonstrates that there are certain groups of people across the world that can be tested to be "LY1 positive" with having a LINE-1 retrotransposon insertion in the centromere...

I have been wondering about this for so long. Do those haplogroup mutations usually only occur in ONE of the father's sperm cells? So you can have two brothers in the same family carrying two different Y haplogroups, even if they are biological brothers by blood, both paternally and maternally...

Found this on Phys.org: Sweeping gene survey reveals new facets of evolution "Who would have suspected that a handheld genetic test used to unmask sushi bars pawning off tilapia for tuna could deliver deep insights into evolution, including how new species emerge? And who would have thought to...

Hi everybody, I have a basic question about if there is a definition to the word mutant for human being. Do we need a lot of mutations in a person to define him as mutant? Is a person who have hemophilia, blindness, red hair, blue eyes and lactose tolerance a mutant being? Thanks for your opinion

While analysing the mtDNA phylogeny, I noticed that most of the common, successful mitochondrial haplogroups were defined by a new mutation in the Coenzyme Q - cytochrome c reductase gene (MT-CYB) encoding the Cytochrome b protein, located between positions 14,747 and 15,887 in the mtDNA...

The human Y chromosome contains only 86 genes, compared to 20,000 genes on the 45 other chromosomes. While most mutations defining Y-DNA haplogroups lie in non-coding regions of the Y chromosome, a few other take place in actual genes. One of the most important among these genes is SRY...
