When neither allele is dominant, the trait that results depends on whether there is codominance or incomplete dominance.
In codominance, that traits coded for by both alleles are expressed. For example, if R codes for red and r codes for white, a flower with the genotype Rr would be white with red spots/splotches/stripes/etc. (or red with white spots) - so it is showing both traits.
In incomplete dominance - a mixture of the two traits is seen. For example, if R codes for red and r codes for white, a flower with the genotype Rr would be pink (a mixture of red a white).

∙ 14y agoINCOMPLETE DOMINANCE: is when neither alleles are dominant or recessive ex. red flower + white flower could= pink flower
Codominance is where both alleles are expressed ex. red flower + white flower = white with red polka dots (or red with white polka dots).

How is it possible to have neither allele dominant?
You have two recessive alleles
What results when one allele is not dominant over the other?
If one allele is not dominant over the other it would mean the alleles are the same so that organism would be a mutant.
What happens to the recessive allele in a heterozygous offspring?
The recessive allele is present, but not shown in complete dominance. This is because the dominant allele is completely dominant over the recessive allele, therefore it is shown, while the recessive allele is hidden.
What is allele masked by the dominant allele?
The Allele That Is Covered By The Dominant Allele Is The Recessive Allele.
What is caused by a dominant allele located on an autosome?
The dominant allele will cause the appearance of the phenotype that this dominant allele represents...
What is it when an allele is neither dominant nor recessive?
this is called codominance when alleles are neither dominant or recessive.
How is it possible to have neither allele dominant?
You have two recessive alleles
What is A pattern of inheritance in which neither allele is phenotypically dominant to the other?
incomplete dominance
What results when one allele is not dominant over the other?
If one allele is not dominant over the other it would mean the alleles are the same so that organism would be a mutant.
What happens to the recessive allele in a heterozygous offspring?
The recessive allele is present, but not shown in complete dominance. This is because the dominant allele is completely dominant over the recessive allele, therefore it is shown, while the recessive allele is hidden.
What contrasting alleles may in some cases result in a case where neither allele is dominant over the other?
If both alleles are recessive, then you will haev a case where contrasting alleles that do not have dominance. Neither allele has the power to be dominant so they will both have equal power of genetics.
Some alleles are neither dominant or recessive and many traits are controlled by what?
Each person has two alleles of one particular gene, which controls one particular characteristic, such as a person's blood group. An allele may be either dominant, recessive, or codominant. A dominant allele would dominate the other allele in the chromosomes, meaning only the dominant allele would contribute to an organism's characteristics. An example of this is the A blood group, which is dominant to the O allele. However, if an individual has both A and B alleles, A and B are codominant, as they both exhibit effects on an organism's characteristics (the blood group). This results in an AB blood group - a combination of the effects of two genes!
When on e allele of a gene masks the presence of the other allele what form is masked?
The recessive allele.
What is allele masked by the dominant allele?
The Allele That Is Covered By The Dominant Allele Is The Recessive Allele.
What is caused by a dominant allele located on an autosome?
The dominant allele will cause the appearance of the phenotype that this dominant allele represents...
What gene is defined as a gene that controls the appearance of a certain trait?
the dominant allele
Which is the dominant allele?
The dominant allele is the trait that shows up in the organism when the allele is present
