Your Inner Reptile Movie Link:
The membrane receptor, Ectodisplasin A (EDA), is expressed in the developing tissue that gives rise to skin. In different embryonic modules, EDA is involved in different genetic regulatory networks to give rise to different structures derived from the skin, including teeth, scales, feathers, hair, sweat glands, claws, fingernails, and mammary glands. In the video, Neil Shubin interviewed Michael Berryman, an actor who plays monsters in lots of movies and shows. Michael Berryman shows a loss of hair, teeth, sweat glands, and finger nails.
What type of factor does EDA interact with? Transcription, Paracrine, or Morphogen ?
Is the mutation to EDA causing heterotopy, heterometry, heterochrony, or heterotypy (Hint #1: three of these results are due to mutations to cis-regulatory elements, and we know that EDA is expressed in multiple locations to give rise to multiple anatomical structures, and that Michael Berryman shows multiple phenotypic abnormalities, and that we should think parsimoniously)?
Are the multiple phenotypic character states shown by Michael Berryman due to linkage disequilibrium or pleiotropy (Hint #2: read Hint #1 above)?
Is the mutation to EDA in Michael Berryman beneficial or deleterious? Why? Think of his anatomy and what he said and give me any old scenario .
We don’t see Berryman’s phenotype occurring everywhere in the human population? Why? Is this mutation dominant or recessive? Will we ever see this phenotype exhibited by this poor guy go away from the human population forever? Why or why not ?
