Armin and Annie are going to have a baby. Annie has dimples in her cheeks (a dominant trait), while Armin does not. You know that Annie's father has dimples in both cheeks, while her mother does not. Her mother must have the recessive trait. Annie's father has the dominant trait, but you don’t know if he is a homozygote or heterozygote. But you still know what Annie’s genotype must be because Annie must have a recessive allele since that is all she could have inherited from her mother. Since Annie has a dimples you know she inherited a dominant allele from her father. What are the chances Armin and Annie’s baby will have dimples? Determine the Phenotype and Genotype and its probability.

Inheritance and Mendelian Genetics

Inheritance means the passing of traits to offspring from parents. These traits could be passed either through asexual reproduction or sexual reproduction. The offspring receives the genetic material from the parents. Mendelian inheritance is a certain biological inheritance that follows the rules and principles laid down by Gregor Mendel in 1865. The initial hypothesis was considered wrong, but other inheritance theories modified the concept of inheritance and thus genetics.
