Genetic dominance is the tendency for offspring to have one characteristic over another. This is due to the way alleles work. Alleles are alternative forms of a gene.
There are recessive alleles, and dominant alleles, and at times two alleles might be codominant. At such times, neither allele dominates over the other, and an intermediate characteristic is expressed in the phenotype (the physical expression of the characteristic).
Example : Blood Group
There are three types of alleles : A, B, and O. O is recessive, but A and B are equally dominant. So A with O becomes A, B with O becomes B, but A with B is AB.
Example : Antirrhinum flower
There are two colour types : Red and white. But the alleles for both types are codominant, and the result is pink.

genetic dominance is like when one side of your genes that you inherit from both your parents are dominant over the other. like if one of your parents have blue eyes and the other has brown eyes, their offspring (you, your brother, your sister, etc.) will most likely have brown eyes because of genetic dominance...

Genes come in two different forms, dominant and recessive. Dominant genes overrule the recessive genes. For example, if you inherit a dominant gene for blue eyes from your mom and a recessive gene for green eyes from your dad, you would have blue eyes because they have genetic dominance.

genetic dominance is when one trait inherited by the parents is shown compared to another one. i.e. one parent has brown eyes (dominant) and one has blue (recessive) its more likely that the child would have brown eyes.
