Daily Science Fact
Australian scientists have found that just a few "letters" out of the six billion that make up the genetic code are responsible for most of the variation in human eye colour. The study, which focused on twins, their siblings and parents, shows - conclusively - that there is no "gene" for eye colour. Differences in eye colour are largely down to "single nucleotide polymorphisms" (SNPs - pronounced "snips"); variations in the sequence of letters that make up a single strand of human DNA.
- We completed the "Natural Selection" notes.
- We watched "March of the Penguins".
