DNA
actually it is not DNA at all, a dominant trait, masks a recessive trait. <3hope this helped. 8)*well that is wrong also, it is the dominant factor. The dominant factor because it masked, or dominated, the factor for the other trait in the pairs. (Holt Biology text book).*Nothing can mask a dominant trait. The only way a dominant trait will not show up in the phenotype is if the genotype is homozygous recessive. Here's an example, if a woman with blue eyes (genotype "ee" homozygous recessive) and a man with brown eyes (genotype "EE" homozygous dominant) have a child, their offspring would have brown eyes (genotype "Ee" heterozygous), even though the recessive allele is there, it does not appear in the phenotype. However, if the father's genotype was Ee, there would be a small chance that the child could end up with blue eyes.
Dominant
Alleles
Recessive
If you are heterozygous this means you carry both a dominant and recessive allele. if you are heterozygous for a recessive trait then you will have a dominant and recessive allele. example: let T represent tall and t represent short. a person with heterozygous for a recessive trait will have 'Tt'.
It is a genetic similarity between two organisms.
Both alleles of one trait are either dominant or recessive. Not one dominant and one recessive. For example, the homogeneous hair of a cat would have both alleles of that trait be the same, say, BB or bb. NOT Bb.The above definition applies in the field of genetics. More generally, the word means "Of the same or similar nature or kind".

The trait could show up in two different forms. Alleles are individual units that determine what trait will be expressed in an offspring. Alleles exist for most traits such as hair color or wing size. Having two alleles simply means that the trait can be expressed in different variation. One trait can have several different alleles.
A trait that masks another trait is called dominant, or a dominant trait.
Heterozygous dominant. Could also be called a masked trait.
The weaker trait is called the recessive trait The stronger one is called the dominant trait

No. A recessive trait is masked by a dominant trait.
The recessive allele.
The trait that is masked is recessive. The trait that does the masking is dominant.
A heterozygote has the genotype of the dominant allele...therefore the recessive trait is the one that is masked.
A recessive trait is one that is not expressed when paired with a dominant trait. It may only be visually evident when both copies of the gene carry the recessive form.
NO, the traits do not disappear they are simply "masked". According to Mendelian theory there are DOMINANT (A) and RECESSIVE (a) traits. When Aa is present the recessive trait is masked therefore it does not show up. These are called alleles.
It is called a dominant trait
The trait that is being masked is recessive, and the trait that is doing the masking is dominant.
