Codominance

In short horn...

Question

In short horn cattle, genes for red (r1) and white (r2) coat colour occur. Crosses between red (r1r1) and white (r2r2) produced (r1r2) roan. This is an example of

Solution

The correct option is D Codominance
Here, both type of traits are transmitting in a single individual. It means both are dominant at a time or codominant, e.g., blood groups of human being and roan colour in cattles.
Codominance is a condition in which two different alleles for a genetic trait, both are expressed. Codominance is a relationship between two versions of a gene. Individuals receive one version of a gene, called an allele, from each parent.
