A regulatory mutation in the PAX3 gene in a population of horses causes the gene to be abnormally expressed in tissues where it is normally silent, disrupting melanocyte migration during embryonic development. This leads to white spotting patterns and congenital deafness due to improper development of pigment and auditory structures. The mutation affects both coat color and auditory system development because of its misexpression in multiple cell lineages during embryogenesis. Which of the following terms apply to this condition?

A sheep producer wants to improve fleece weight in their flock of Merino sheep. In the current flock, the average fleece weight is 8.2 pounds per ewe.
