Dominant And Recessive Alleles In Genetics

The video tutorial explains the concept of dominant and recessive alleles. It begins with an introduction to alleles and their role in genetics, followed by how they are represented using uppercase and lowercase letters. An example using cat fur color illustrates the dominant-recessive relationship. The video concludes with a brief mention of upcoming topics like homozygous and heterozygous alleles.
