Genotypes usually involve some combination of dominant and recessive alleles. what is the most common inheritance pattern?

Most common inheritance pattern are Autosomal dominant, Autosomal recessive, X-linked dominant and X-linked recessive.

Step-by-step explanation:

Genotype constitutes the genetic make-up of the cell. it is the set of genes in our DNA, which is responsible for particular traits.  

Most common inheritance pattern are Autosomal dominant(examples are: Huntington disease), Autosomal recessive(examples are: Sickle cell anemia and Cystic fibrosis), X-linked dominant(examples are: Fragile X syndrome), and X-linked recessive(examples are: Hemophilia).

Dominant inheritance means an abnormal gene from parent can cause the disease. On the other hand recessive inherits two mutated genes that is one is carrier and other is affected, which can cause disease.
