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.

his research revealed two genetically different groups of prokaryotes, which justified splitting kingdom monera into two kingdoms. the genetic and cellular differences were so great, that these two kingdoms were eventually placed into different domains in the current three-domain system.
