Genetics: Characters and Alleles

This video tutorial explains the difference between alleles and traits. It begins with an introduction to alleles, describing them as variants of a gene, using the example of a gene for height with two forms: capital T and small T. The video then defines character as an identifiable feature and explains that traits are variants of a character, such as tallness and dwarfness for the character of plant height. The tutorial concludes by comparing alleles and traits, highlighting that alleles are different forms of a gene, while traits are different forms of a character.
