Verified step by step guidance1
Understand the concept of multifactorial traits: These are traits that are influenced by multiple genes and environmental factors, leading to a wide range of phenotypes.
Recognize that multifactorial traits often exhibit continuous variation, meaning they do not fall into discrete categories but rather show a spectrum of phenotypes.
Identify that multifactorial traits are affected by environmental factors, which can modify the expression of the genes involved.
Recall that Mendelian inheritance patterns refer to traits controlled by a single gene with clear dominant and recessive alleles, leading to predictable inheritance patterns.
Conclude that multifactorial traits do not follow Mendelian inheritance patterns because they involve multiple genes and environmental influences, resulting in complex inheritance patterns.
