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 is a person who has one recessive allele for a trait and one dominant allele for the same trait and is able to pass in the trait on to their offspring?

That is heterozygous. Some scientist call these "hybrids"(no joke)The person is heterozygous for that trait and will have the dominant phenotype.An organism with both a dominant and recessive allele for a specific trait is called an heterozygote. They are heterozygous for this trait.


Allele that is fully expressed is referred to as?

No, it is referred to as dominant


What gene is masked if it is paired with a dominant gene?

The different forms of a gene are called alleles. In Mendelian genetics, a gene has a dominant allele and a recessive allele. The dominant allele masks the recessive allele if present. So there are two possible dominant genotypes: homozygous dominant, in which both dominant alleles are present; and heterozygous, in which one allele is dominant and the other allele is recessive. The only way to express a recessive trait is to have the homozygous recessive genotype.


Why is it that a person with an allele for a particular trait may not have a phenotype that shows the trait?

a dominant allele will express its trait , as well as be carried by the person. the word carrier is commonly used for a person who bears an allele which does not express itself(i.e. a recessive gene).

An allele that is dominated or cover up by another allele is called what?

An allele that is dominated or covered up by another allele is called a recessive allele. This means that the trait associated with the recessive allele is only expressed when an individual carries two copies of that allele.


What is allele masked by the dominant allele?

An allele that is masked by the dominant allele is called a recessive allele. When an individual has one dominant allele and one recessive allele, only the trait determined by the dominant allele will be expressed. The recessive allele will only be expressed if an individual has two copies of it (homozygous recessive).


Can recessive allele able to persist if the environment does not favor it?

The recessive allele can only persist in a favorable environment. The proper environment is for two recessive alleles to exist together. Then they would function properly as if the two were a dominant allele.


Is albinism controlled by a dominant allele or by a recessive allele?

Recessive allele.


Does a recessive allele need another recessive allele to be expressed?

Yes, a recessive allele needs to be paired with another recessive allele in order to be expressed. This is because recessive alleles are only expressed when an individual has two copies of the recessive allele, one from each parent. If an individual has one dominant allele and one recessive allele for a particular trait, the dominant allele will be expressed.


What is the term for an allele that is not expressed in the phenotype of a heterozygous individual?

Is albinism controlled by a dominant allele o recessive allele?

It is controlled by a recessive allele.


What allele is covered up by the dominant allele?

An allele that's masked by a dominant gene is called a "Recessive"recessiverecessive traitThe recessive allele. Often depicted as the "small r" in examples: Rr, R=dominant, r= recessive.


An allele that is hidden by other alleles is called?

i think the answer your lokking for is recessive Recessive is when you have a trait in your genome but it doesn't show in your physical appearance


How is a recessive allele from a dominant allele?

its different because adominant allele is in charge


What is it Dominant allele What is a recessive allele?

A genotype in which there are both a dominant and a recessive allele is called heterozygous.


Why will a recessive allele not show up if?

A recessive allele will not show up if there is a dominant allele present.
