What contrasting alleles may in some cases result in a case where neither allele is dominant over the other?
SimphiweMpilo
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.

How is it possible to have neither allele dominant?
You have two recessive alleles
What is it when an allele is neither dominant nor recessive?
this is called codominance when alleles are neither dominant or recessive.
When the alleles of a gene pair are expressed differently but neither is dominant to the other?
Codominance means that neither allele can mask the expression of the other allele. An example in humans would be the ABO blood group, where alleles A and alleles B are both expressed.
When neither allele is dominant what are they expressed as?
Both of the alleles must be recessive. The trait expressed is a recessive trait.
What is codominance?
It's like incomplete dominance, but instead of one allele not being completely dominant for a trait, both alleles for that specific trait are dominant.A condition in which neither of two alleles of a gene is dominant nor recessive
When neither allele is dominant (they are both expressed)?
Both of the alleles must be recessive. The trait expressed is a recessive trait.
Is a situation in which a dominant allele completely masks a recessive allele for a gene.?
If you have 2 dominant alleles, the gene will be dominant, if you have 2 recessive alleles, the gene will be recessive. But if you have 1 recessive and 1 dominant, the Dominant allele will mask the recessive one.
What makes dominant alleles different from recessive alleles?
It's in the word! Dominant means bigger or stronger or greater. So the dominant allele is the stronger gene that is going to show whereas the recessive allele is still in you, but is overshadowed by the dominant allele.
What are the circumstances under which dominant alleles will be expressed?
A dominant allele will be expressed when an allele pair is homozygous or heterozygous dominant.
Gene pairs consists of two dominant alleles or two recessive alleles?
A gene pair that consists of a dominant allele and a recessive allele is called a heterozygous gene. A homozygous gene, meanwhile, is a gene pair consisting of two dominant alleles or two recessive alleles.
What is the difference between dominant alleles and recessive alleles?
dominant-appears in first generation recessive-seems to dissapear
What is recessive and dominant mean?
I am pretty sure the recessive and dominant alleles you are talking about are covered in Biology. Recessive alleles are basically alleles that are received from both parent's DNA that are carries, (dd). However, dominant alleles are (exactly what it says) always expressed. If there is one dominant allele and one recessive allele the dominant allele overpowers the recessive. (DD) and (Dd)overpowers (dd).
