Question

decide which type of inheritance best matches the definition.

1. multiple genes interact to determine the phenotype.
2. two alleles are dominant, resulting in offspring that show both phenotypes.
3. one gene has several different forms, resulting in more than two phenotypes.

Explanation:

1. This describes a type of inheritance where multiple gene loci contribute to a single phenotype, with interactions between the genes shaping the observable trait.
2. This refers to an inheritance pattern where neither allele is recessive, so both traits encoded by the dominant alleles are fully expressed in the offspring.
3. This is an inheritance pattern where a single gene has three or more distinct allele variants, leading to a broader range of possible phenotypes than typical two-allele systems.

Answer:

1. Polygenic Inheritance
2. Codominance
3. Multiple Alleles
