Complete linkage is exhibited when the genes for a particular character are present very close to one another. It is.due to non-break in the gene combination situated on a chromosome. On the other hand, incomplete linkage occurs when the genes for different characters are separated at the time of gamete formation due to breaking and ...

WebA variation on incomplete dominance is codominance, in which both alleles for the same characteristic are simultaneously expressed in the heterozygote. An example of codominance occurs in the ABO blood groups of humans. The A and B alleles are expressed in the form of A or B molecules present on the surface of red blood cells. WebIn our example, the genes are ^3 3: The purple gene, with a dominant pr ^+ + allele that specifies normal, red eyes and a recessive pr allele that specifies purple eyes.
