To determine the pattern of inheritance, we need additional information about the traits being examined. Here's a brief description of each form of inheritance to help you decide:

  1. Incomplete dominance: This occurs when the phenotype of the heterozygote is intermediate between the phenotypes of the homozygotes. For example, in snapdragons, red flowers (RR) and white flowers (rr) can produce pink flowers (Rr).

  2. Polygenic inheritance: This is where multiple genes influence a trait, leading to a continuous range of phenotypes, such as skin color or height.

  3. Complete dominance: In this scenario, the phenotype of the heterozygote is the same as that of one of the homozygotes. For example, if a dominant allele (R) produces red flowers and a recessive allele (r) produces white flowers, then both RR and Rr individuals will have red flowers.

  4. Codominance: This occurs when both alleles in the heterozygote are fully expressed, resulting in a phenotype that displays traits from both alleles. An example is AB blood type where both A and B alleles are expressed.

If you can provide specific examples or details about the traits involved in your question, I can help identify the pattern of inheritance more accurately.
