What is the type of trait that can be masked?
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.
What is meant by complete dominance?
DefinitionnounA kind of dominance wherein the dominant allele completely masks the effect of the recessive allele in heterozygous condition.SupplementFor instance, an individual carrying two alleles that are both dominant(e.g. AA), the trait that they represent will be expressed. But if the individual carries two alleles in a manner that one is dominantand the other one is recessive, (e.g. Aa), the dominant allele will be expressed while the recessive allele will be suppressed. Hence, theheterozygote (Aa) will have the same phenotypeas that of the dominant homozygote (AA). This condition is called complete dominance.
Why are dumpy wings recessive or dominant trait?
Dumpy wings in fruit flies are a recessive trait. This means that an individual must inherit two copies of the dumpy wing allele (one from each parent) in order to exhibit the dumpy wing phenotype. Dominant traits, on the other hand, only require one copy of the allele to be expressed. In the case of dumpy wings, the presence of the wild-type allele (normal wings) masks the expression of the dumpy wing allele, making it recessive.
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 factor that seems to disappear due to a dominant allele?
An allele is one particular form of a gene. A large population of living things typically have several different allele for any particular gene. For example, one important gene in humans determines blood type compatibility. That gene comes in 3 different alleles -- A, B, and O. Most plants and animals are diploid -- they have 2 of each gene, one inherited from each parent. For example, any one human has one of six possible genotypes for that gene: AA, BB, OO, AB, AO, BO. A recessive allele seems to disappear when paired with a dominant allele. If something has a dominant and recessive allele, the dominant will overshadow the recessive, but the recessive will still be there (just not showing). For example, the O allele is recessive when paired with the A allele, which is dominant, and so humans with the AO genotype as well as the AA genotype have "type A blood". Only humans with the OO genotype show "type O blood". According to the Wikipedia "allele" article, some people once thought that all genes had only one "normal" allele, which was both common and dominant, and all other versions of that gene (all other alleles) were rare and recessive. However, most genes have many different "normal" alleles, whose frequencies vary from one population to another. With some genes, the most common allele is recessive.
What type of allele masks the expression of the recessive allele and is therefore expressed in the heterozygous?
A dominant allele will mask the prsence of a recssive allele
Is an allele that produces a trait in the heterozygous condition recessive?
No. A recessive allele will not be expressed phenotypically in the heterozygous state. A recessive allele can only be expressed phenotypically in the homozygous state.
What is it called having a dominate and recessive allele?
Having a dominant and recessive allele is known as Mendelian inheritance, named after Gregor Mendel, the scientist who first described it. In this type of inheritance, the dominant allele masks the expression of the recessive allele in heterozygous individuals.
What type of trait prevents the other type from being seen?
A recessive trait. When a recessive allele is with a dominant allele, only the dominanate trait can be seen.
What is simple dominance?
Simple dominance is a concept in genetics where one allele (gene variant) masks the expression of another allele at the same locus. This results in the dominant allele being expressed phenotypically, while the recessive allele is not expressed. This type of inheritance pattern is common in traits like eye color or hair texture.

What type of allele is masked when a dominant allele is present?
The recessive allele is masked when a dominant allele is present. Dominant alleles are expressed over recessive alleles in heterozygous individuals.
What does recessive allele mean?
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.

What type of allele is known for skipping a generation?
Recessive alleles are known for skipping a generation. This is because the phenotype associated with a recessive allele is only expressed when an individual inherits two copies of the recessive allele, one from each parent. If one parent carries the allele but does not exhibit the trait, it can appear to "skip" a generation before being expressed.
