If the four dominant alleles for intelligence are WXYZ and the recessive alleles for intelligence are wxyz, which of the following would be the most common inheritance pattern?

Question

Quizplus · Accepted Answer

The inheritance pattern for intelligence would be polygenic inheritance, meaning that it is influenced by multiple genes. The given alleles WXYZ and wxyz may represent different genes or variations within the same gene. Therefore, a combination of different alleles is most likely to influence intelligence. 
Choice D, WwxxYYzZ, represents a combination of two dominant alleles (W and Y) and two recessive alleles (x and z), which is a realistic possibility for polygenic inheritance. 
Choice C, WWXXYYZZ, represents only dominant alleles, which is less likely to occur in a polygenic inheritance pattern. 
Choice A, WWwwYYyy, and Choice B, WWxXyYZZ, also do not represent a realistic combination of alleles in a polygenic inheritance pattern.
