Mendel’s “heritable factors” were discovered many years later to be ___________.

 Mendel’s Law of Segregation states that during meiosis, the genes that control each trait separate, and only ____ from each pair is/are passed on to the offspring.

 Mendel’s finding that the inheritance of one trait had no effect on the inheritance of another became known as the

Genes located on homologous chromosomes may have alternate forms that control different versions of a trait.  

       These alternate versions of a trait are called ________.
