Which of the following is NOT a characteristic of Mendelian inheritance?

Correct Answer: Incomplete dominance

Step 1: Understand what Mendelian inheritance is. It refers to the basic principles of heredity discovered by Gregor Mendel, which include traits being determined by single genes with dominant and recessive alleles.
Step 2: Identify the characteristics of Mendelian inheritance. These include clear dominant and recessive traits, segregation of alleles during gamete formation, and independent assortment of traits.
Step 3: Learn about incomplete dominance. This is a situation where neither allele is completely dominant, resulting in a phenotype that is a blend of the two parental traits.
Step 4: Compare incomplete dominance with Mendelian inheritance. Since incomplete dominance does not follow the dominant-recessive pattern, it is not a characteristic of Mendelian inheritance.
Step 5: Conclude that the answer to the question is incomplete dominance, as it does not fit the Mendelian inheritance model.
