When one allele for a particular trait masks or overrides another allele for a trait, it is called dominance. The allele that is masked is called the recessive allele. The allele that is dominant will determine the phenotype.

What one allele of a gene masks the presence of the other allele what form can be seen in the phenotype?
When one allele for a particular trait masks or overrides another allele for a trait, it is called dominance. The allele that is masked is called the recessive allele. The allele that is dominant will determine the phenotype.
When on e allele of a gene masks the presence of the other allele what form is masked?
The recessive allele.
When one of a gene masks the presence of the other allele what form is masked?
The recessive allele.
What does a dominant allele always do?
It overpowers and masks the other allele
Does a dominant allele mask a ressessive allele?
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.

What is an allele that always shows up in an organism's phenotype called - an allele that masks the other allele?
The dominant allele.
When on e allele of a gene masks the presence of the other allele what form is masked?
The recessive allele.
When one allele of a gene masks the presence of the other allele what form is masked.?
recessive A+
When one of a gene masks the presence of the other allele what form is masked?
The recessive allele.
Why do we call some alleles dominant?
because it dominates the phenotype
What is it called when an allele masks the other allele?
Dominance.
What does a dominant allele always do?
It overpowers and masks the other allele
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 only one character seen in the first filial generation?
because the dominant allele usually masks the other allele present in the combination (one from each parent)
