Mendelian Inheritance in Humans

Mendelian Inheritance in Humans Classroom Activity

Name: ____________________________________________

Human have several single-gene traits that are easy to observe and which are controlled by genes that have only two alleles. Based on the specific combination of alleles (AA, Aa = dominant phenotype; aa = recessive phenotype) the trait is either present or absent. There is no “in between”. Many other human traits, such as eye color and height are due to several pairs of genes, and the phenotypes show a continuous range of variation.

For the traits described in the following list, determine your phenotype and possible genotype.

then compare with a friend and describe what the chances of your hypothetical kid would be like.
