Atrait has only two observable variations. what is the pattern of inheritance for this trait? codominant incomplete dominance polygenic recessive

Codominant

Explanation:

Codominance can be defined as a situation in which heterozygous organisms express both alleles of a gene at the same time, that is, in codominance an individual has a characteristic that has only two observable variations. In these situations, relationships of dominance and recessiveness are not perceived, as both alleles express themselves fully.

Another characteristic of codominance concerns the phenotype. In situations of dominance and recessiveness, we observed two phenotypes, since the heterozygote presents the dominant allele phenotype. However, in the case of codominance, the heterozygote phenotype is distinct from that observed in homozygotes.

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
