Question

recalling terms related to non-mendelian inheritance
codominance explains inheritance resulting in two dominant alleles being expressed in the offspring, with neither trait being masked.
complete
incomplete dominance explains traits that are neither dominant nor recessive, resulting in a third phenotype in the offspring that appears to blend the traits from the parents.
complete
polygenic traits are traits resulting from the expression of multiple genes from different loci of different chromosomes.
complete
is a protein found in blood that is represented by a + or - sign, which affects the types.
rhesus factor
antigen factor
antibody factor

Explanation:

The Rhesus factor (Rh factor) is a protein found on the surface of red blood cells. It is represented by a + or - sign (e.g., Rh+ or Rh-). This factor is important in blood typing and can have implications for pregnancy (e.g., Rh incompatibility between mother and fetus). The other options, "Antigen factor" and "Antibody factor," are more general terms. Antigens are substances that can trigger an immune response, and antibodies are proteins produced by the immune system to fight antigens. But specifically, the protein in blood with a +/ - sign representation is the Rhesus factor.

Answer:

Rhesus factor
