What is the dominance -recessive interaction of an allele pair?

This depends on the type of dominance relationship. You can have true dominance, in which case if the allele pair contains a dominant allele, the dominant trait will be expressed. In this case the recessive trait will only be exhibited if both alleles are recessive.
A second case is that of codominance. In this case, two alleles are codominant, so if you have one of each, both traits will be expressed.
A third case is that of incomplete dominance. In this case, if you have a dominant and a recessive allele, you will get a trait which is a mixture of both traits. A good example is when you breed a red flower and a blue flower and get a purple flower as progeny.
Other things, like dominance series, also exist. However this information should answer your original question.

What is the term for an allele that is not expressed in the phenotype of a heterozygous individual?
incomplete dominance source: PH Bio textbook
What type of allele masks the expression of the recessive allele?
Two recessive alleles can not take over a dominant allele because there are only two alleles in a pair. This can only happen if there is a mutation because the dominant always takes over the recessive.
How does hemophilia progress?
Hemophilia is a recessive allele condition. Men can get hemophilia alot easier than women as the allele is found on the XY Chomosome pair. With men. they do not have the extra "tail" on the Y chromosome compared to the XX with a female. If the person has the recessive allele on the X chromosome and this person is male, they will be a hemophiliac as they do not have a 'pair' allele which could be dominant to stop the condition expressing itself. On a female, if there is a recessive (hemophilia) allele on one of the X chromosomes but on the other is a Dominant (normal) allele then she will be a carrier of the faulty gene but will not suffer from the condition herself. If the female have a recessive (faulty) gene on each of the XX chromosomes, then she will be a sufferer of the disease.
What kind of gene pair that consists of a dominant allele and a recessive allele?

What are the priciples of dominance?
A gene is composed of two alleles ( one from mom and one from dad ) and one of these alleles is " dominant " over the other in the expression of protein product and the " dominant " allele is seen in the phenotype.
What is the term for an allele that is not expressed in the phenotype of a heterozygous individual?

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 weaker allele in a pair of genes?
Recessive Allele
What is a gene pair that consists of a dominent allele and a recessive allele?
Heterozygous dominant pair.
What is the name of the gene pair that consist of a dominant allele and recessive allele?
The name of the gene pair that consists of a dominant and recessive allele, i.e. (Xx) will be a heterozygous allele. In this situation, the characteristics of the dominant characteristic will mask that of the recessive allele. People have have a heterozygous genotype may be carriers for diseases that reside on the recessive allele.
What is called when you have a pair of genes that cnsits of a dominant allele and a recessive allele?
heterozygous
What gene pair that consists of a dominate allele and a recessive allele?
the tiger of ireland
The weaker of two alleles in a pair that is often masked by the dominant allele?
The recessive allele.
What is it when you have a gene pair that consist of two dominate alleles and two recessive alleles?
The name of the gene pair that consists of a dominant and recessive allele, i.e. (Xx) will be a heterozygous allele. In this situation, the characteristics of the dominant characteristic will mask that of the recessive allele. People have have a heterozygous genotype may be carriers for diseases that reside on the recessive allele.
Which form of gene pair is expressed when both dominant and recessive are present?
If the gene is governed by a dominant and recessive allele, then if the dominant allele is present, the dominant trait will be expressed. If both alleles are recessive, then the recessive trait will be expressed.
What do the terms dominant and recessive mean?
ACCORDING TO GREGOR MENDEL'S LAW OF DOMINANCE:- Dominant Allele refers to the expressed trait in a pair of genes,while the dormant,suppressed trait is the recessive allele.
What allele pair would show co-dominance of blood types?
Type AB
