Explain why genes used by mendel did not show epistatic?

Mendel's choice of genes for his experiments did not show epistasis because he specifically selected genes that exhibited independent assortment. Epistasis is a phenomenon where the expression of one gene is influenced by another gene. However, Mendel intentionally chose traits that were controlled by genes located on different chromosomes or genes that were far apart on the same chromosome. This ensured that the genes he studied would segregate independently during gamete formation, and their expression would not be influenced by other genes.

By selecting traits such as seed color (yellow or green) and seed texture (smooth or wrinkled), which were controlled by genes located on different chromosomes, Mendel ensured that the inheritance of one trait would not affect the expression of the other trait. This allowed him to observe the simple patterns of inheritance, such as the 3:1 ratio in the F2 generation, which became the basis for his laws of inheritance.

In summary, Mendel's choice of genes for his experiments did not show epistasis because he deliberately selected genes that exhibited independent assortment, ensuring that the expression of one gene would not be influenced by another gene.
