+ | Despite tongue rolling being probably the most commonly-used example of a genetic trait in humans, it is a myth that a single gene is responsible for the skill. Studies demonstrate that tongue rolling is influenced both by genetics and by the environment. [([[http:// | ||
- | It is a myth that earwax is dependable on genetics. A single gene is not responsible for a kind of earwax one has, whether it is wet or dry and what color. The wet wax allele is also not dominant over the dry one. [([[http://udel.edu/~mcdonald/mythearwax.html]])]. | + | ==== The North African blue atlas butterfly ==== |

+ | The amount of eumelanin and pheomelanin determine the hair color in humans. Eumelanin is dark brown, and pheomelanin is reddish. People who have large amounts of pheomelanin have red hair. [([[http:// | ||

+ | Johann Friedrich Miescher (1844-1895) was a Swiss researcher of cell metabolism and the discoverer of nucleic acids. In 1869, he isolated nucleic acids, which he called nuclein, from oil-soaked bandages of patients. He later discovered that they are found mainly in chromosomes. [([[https:// | ||
- | ===== One gene is not responsible for tongue rolling ===== | + | ==== Taste and smell ==== |
+ | Only 3 genes are associated with sight, 2 with hearing, 5 with taste, and 1000 with smell. Fewer genes are linked to hearing - 2. 5 genes are linked to taste, while 1000 genes are linked to smell! [([[https:// | ||
