Dogs and humans have a long shared history, but how alike are we really? When the structure of DNA was discovered and we gained the ability to sequence both human and animal genomes, it was no great surprise to learn that we had a lot in common with our animal friends. Humans and anim...
2011). However, recent research on Neanderthal nuclear DNA has found evidence for limited admixture: a small portion (up to ~4%) of the genomes of non-Africans so far examined may derive from Neanderthals, suggesting that interbreeding probably occurred in the Near East during the earliest ...
Humans reproduce sexually, which means one cell’s genetic information has to hook up with another cell’s genetic information to make a new human. In this process, genetic traits are passed on from parents to child. You might inherit your father’s nose, or your mother’s curly hair. ...
Because the translocation/inversion breakpoints were determined with karyotyping, the actual breakpoints at the molecular level are not known. To estimate the size, we considered the smallest possible segmental imbalances by using the chromosomal band boundary closest to the telomere. The segment size es...
