some traits, like height or intelligence are determined by many genes interacting and so it is too complicated for punnett squares. what type of inheritance is this?
classic mendelian genetics (dominant/recessive)
incomplete dominance
codominance

Explanation:

Question 1 (Blue butterflies and red butterflies make purple butterfly babies)

In incomplete dominance, the heterozygous phenotype is an intermediate (blend) of the two homozygous phenotypes. Blue and red blending to make purple fits this, as opposed to codominance (both traits expressed separately) or classic Mendelian (dominant/recessive with no blend) or polygenic (multiple genes).

Polygenic traits are controlled by multiple genes, which matches the description of traits like height/intelligence being determined by many interacting genes. Classic Mendelian is single - gene dominant/recessive, incomplete dominance and codominance are single - gene non - Mendelian patterns.

Codominance is when both alleles are fully expressed in the heterozygote, resulting in a phenotype that shows both traits (like stripes from orange and yellow). Incomplete dominance is a blend, classic Mendelian is dominant/recessive, and polygenic is multiple genes.

Answer:

Incomplete dominance
