Work Step by Step
While many traits are inherited in a Mendelian pattern, not all traits follow Mendelian inheritance. Some traits are influenced by multiple genes (polygenic inheritance), some show incomplete dominance or codominance, and others are influenced by environmental factors. Additionally, traits located on sex chromosomes (such as X-linked traits) may have inheritance patterns that differ from Mendelian inheritance. Therefore, it's not accurate to say that all traits are inherited in a Mendelian pattern.
