Question: Another mutation has occurred in the Andean condor, which is further endangering the survival of the species: Frizzled feathers. This trait results from a mutation in the a-keratin gene, and this mutation causes the feathers to curl. If two frizzled condors happen to mate, rather than producing offspring with frizzled feathers, one observes that 25% of the condor chicks have normal (straight) feathers; 50% have frizzled (curly) feathers, and an unfortunate 25% have “over-frizzled” feathers, which are extremely brittle and resemble pipe cleaners. Birds having this “over-frizzle” trait have great difficulty flying. When a condor that is homozygous for the normal feather allele is mated with one of these “over-frizzled” birds, all of the chicks will have frizzled feathers. Please NAME and EXPLAIN the genetic phenomenon described here.
