[7] Although the "free" vs. "attached" appearance of earlobes is often presented as an example of a simple "one gene – two alleles" Mendelian trait in humans, earlobes do not all fall neatly into either category; there is a continuous range from one ...

  3. Simple Mendelian genetics in humans - Wikipedia

    en.wikipedia.org/wiki/Simple_Mendelian_genetics...

    Mendelian traits behave according to the model of monogenic or simple gene inheritance in which one gene corresponds to one trait. Discrete traits (as opposed to continuously varying traits such as height) with simple Mendelian inheritance patterns are relatively rare in nature, and many of the clearest examples in humans cause disorders.

  7. Stapes - Wikipedia

    en.wikipedia.org/wiki/Stapes

    Otosclerosis is a congenital or spontaneous-onset disease characterized by abnormal bone remodeling in the inner ear. Often this causes the stapes to adhere to the oval window, which impedes its ability to conduct sound, and is a cause of conductive hearing loss. Clinical otosclerosis is found in about 1% of people, although it is more common ...

  8. Malleus - Wikipedia

    en.wikipedia.org/wiki/Malleus

    The malleus, or hammer, is a hammer-shaped small bone or ossicle of the middle ear. It connects with the incus, and is attached to the inner surface of the eardrum. The word is Latin for 'hammer' or 'mallet'. It transmits the sound vibrations from the eardrum to the incus (anvil).

    The defect is located just superior to the tympano-mastoid suture line in the posterior ear canal. Following identification of the spine of Henle it is possible to follow the tympano-mastoid suture line medially towards the annular ring. At this location the Chorda Tympani Nerve is often identified.
