Recessive allele disorders are just as they sound - they are disorders that are a result of a prevalent recessive allele in one's genetic makeup. A recessive allele disorder will rarely occur since it is dependent on the crossing of two heterozygous parent cells, but it can lead to interesting consequences. An example of a recessive allele disorder is hemophilia - the body's inability to clot blood - and it has affected much of the European royalty in history, such as Queen Victoria of Great Britain.
In classic genetics: AA or Aa for autosomal dominance; for sex-linked dominance, females will need XX or Xx, while males will need Xy It gets more complicated with epistasis and other factors that modulate the genes.
A dominant alle masks the expression of the recessive trait in a heterozygous genotype, a recessive allele is the phenotpye expressed is the recessive trait.
This type of inheritance represents alleles at the same locus where one is recessive to the other. The dominant phenotype occurs in all heterozygous offspring as well as the homozygous dominant offspring. This yields a 3:1 phenotype and a 1:2:1 genotype.
A dwarf plant cannot have a dominant allele because it has recessive genes. You should look at the genotype, punnett square, of a dwarf plant for the probability of the dwarf plant having a dominant allele. :):):):) hoped this helped, otherwise, sorry! did my best....

Although not all combinations have a dominant allele, dominance does play a role in determining the phenotype when present. In some cases, both alleles may be expressed equally or result in a unique trait differing from the dominant alleles. It's essential to consider the influence of both dominant and recessive alleles in genetic inheritance.
The type of trait that can be masked is known as a recessive trait. In genetics, recessive traits require two copies of the recessive allele (one from each parent) to be expressed phenotypically, while a dominant allele can overshadow or mask the expression of the recessive allele. As a result, individuals with one dominant and one recessive allele will display the dominant trait, concealing the presence of the recessive trait.

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.

In diploid organisms (those with two copies of each gene carried on separate chromosomes), one of the copies of a given gene may differ from the other copy of the same gene on the twin chromosome. In some cases one version of the gene (the dominant allele) has the effect of 'masking' the activity of the other (the recessive allele); that is, the presence of the dominant allele negates the effect of the recessive allele on the organism's phenotype. There are many mechanisms which can cause this phenomena, and it depends on the particular genes involved, but a simple model is one where the recessive allele is a biochemically inactive version of the dominant allele. In this case the dominant allele would mask the effect of the recessive allele by providing an active version of the gene. The dominant phenotype would be the one which shows the downstream effects of this activity, and the recessive phenotype one which shows the downstream effects of a lack of activity. The dominant allele is said to 'mask' the recessive allele because only one copy is required to result in an elimination of the recessive phenotype, whereas all copies of the gene must be the recessive allele to result in the recessive phenotype.
It's actually just heterozygous. That means that one allele is dominant and one allele is recessive. The result is a dominant trait, but the recessive gene may come back in future generations.
A gene with one completely dominant allele and two recessive alleles can produce two different traits. The dominant allele will express its trait regardless of whether it is paired with another dominant or a recessive allele, while the two recessive alleles will express their trait only when paired together. Therefore, the possible combinations of alleles result in one dominant trait and one recessive trait.
