Some Chickens Have a Dominant Frizzle Gene That Leads to the Development

Multiple Choice

Some chickens have a dominant frizzle gene that leads to the development of feathers that curl outward rather than lying flat against their bodies as in standard chickens. Aside from these "frizzled feathers," chickens with this dominant allele also tend to have higher metabolic rates and produce fewer eggs than chickens that carry the recessive version of this gene. Thus, this gene exhibits __________.

A) pleiotropy
B) polygenic inheritance
C) incomplete dominance
D) codominance
