Question
8. Fainting goats are a breed of goat that was selectively breed for the phenotype myotonia congenita -they don't actually faint. This phenotype is characterized by paralysis of skeletal muscles whenever the muscles experience a signal to tense up. In normal goats (and all other mammals), this signal occurs in response to being startled and lasts a few milliseconds. In fainting goats, the paralysis lasts several seconds. The goats become statue-like when startled but are still subject to the laws of physics, i e. conservation of momentum. Below is a pedigree analysis of goats expressing the myotonia congenita phenotypeExplanation / Answer
