b. 25 genes
c. 35 genes
d. The number of genes doesn't make a difference

***B*** ∻Key Concept∻ ⚹Polygenic inheritance and the Central Limit Theorem⚹ ∻Explanation∻ ⚹When multiple genes are involved in determining a phenotype, the distribution of that phenotype tends to follow a normal distribution due to the Central Limit Theorem. The more genes involved, the closer the distribution will be to a normal distribution. Therefore, 25 genes involved would result in a phenotype distribution closer to a normal distribution compared to 5 or 35 genes, assuming the number of genes is the only variable changing.⚹◊What is the relationship between the number of genes involved in determining a phenotype and the distribution of that phenotype?⍭ Generate me a similar question◊
