Drag the tiles to the correct boxes to complete the pairs. Identify the types of inheritance based on the expression of alleles in the organism. dominant recessive multiple presences of many alleles for the trait to be expressed  the presence of two alleles for the trait to be expressed  presence of a single allele for the trait to be expressed 
Answer:
- multiple
- recessive
- dominant
Explanation:
- Autosomal dominant inheritance characterizes because the dominant allele completely hides the expression of the recessive allele. Even when both dominant and recessive alleles are present in the genotype, only the dominant trait will be expressed. Only one dominant allele is enough to express the dominant phenotype.
- Autosomal recessive inheritance characterizes by the expression of the recessive trait. Two copies of these alleles are needed to express the recessive phenotype and no dominant alleles.
- Polygenic heritability occurs when a trait is due to the action of multiple genes that can also have more than two alleles. This can cause many different combinations that are the reason for genotypic graduation.
