Greetings from New York, this is Dr. Jerry E. I'm so glad you asked this question, let me give you some medical information now. No, canker sores are mouth ulcers usually caused by a viral illness such as a cold.I know they are painful. They're not related to the advair or flonase. You can mix 50% maalox and 50% benadryl solution and swish it and spit it out 3 times a day for relief.reetings from New York, this is Dr. Jerry E.

Answer by Brooke Schnoor. Confidence votes 36. A dominant allele is an allele that can take over a recessive allele, so if you have a dominant allele and a recessive allele, then the offspring will most likely have a dominant allele over a recessive allele.The dominant allele is expressed over the recessive allele.nswer by Brooke Schnoor.

1 For example, the allele for brown eyes is dominant, therefore you only need one copy of the 'brown eye' allele to have brown eyes (although, with two copies you will still have brown eyes). 2  If both alleles are dominant, it is called codominance. These different versions of a gene are called alleles. 2  Alleles can be either dominant or recessive. 3  Dominant alleles show their effect even if the individual only has one copy of the allele (also known as being heterozygous).
