When an allele mask the presence of another allele it is said to be?

Dominent. Simple- you have two types of Alleles, Dominent and Reccessive. Imagine a punnet square for the allele that causes albinoism (A).
One parent has Aa, or one dominent allele and one reccessive allele for the trait. If the dominent skin-tone gene wasn't there (A), then it would be AA and he would be an albino. But since he has a dominent allele, he has normal color.
If he made a baby with another Aa combination, they would have 25% chance of having an AA baby with no reccessive allele, a 50% chance of having an identical Aa combination, and a 25% chance of having an albino baby, AA.

Note: not all alleles are either dominant or recessive.

How are two traits that have Dominant and Recessive alleles inherited?
The trait received is recessive.
Gene pairs consists of two dominant alleles or two recessive alleles?
A gene pair that consists of a dominant allele and a recessive allele is called a heterozygous gene. A homozygous gene, meanwhile, is a gene pair consisting of two dominant alleles or two recessive alleles.
If a disease can be passed on from one person to another it is said to be?
It is said to be communicable or contagious.
When a gene inherited from one parent masks the expression of the gene inherited from the other parent that gene is said to be?
A gene whose phenotypic expression is masked by the presence of another is generally called the recessive gene. However, it can still be passed onto offspring.
What are pure alleles?
Alleles come in pairs. Organisms inherit one allele from each parent organism with sexual reproduction. If the alleles are the same, they could be said to be pure alleles. The science term is monozygous.
When the expression of one allele is masked by the presence of another is said to be?
Recessive
When one allele shows dominance over another allele?
When one allele shows dominance over another it is masking the expression of the other allele which is called "recessive".The word for this is complete dominance.
When the expression of one is masked by the presence of another is said to be?
Recessive
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.
A population in which allele frequencies do not change from generation to generation is said to be in?
A population in which the allele frequencies do not change from one generation to the next is said to be in equilibrium.
What happens when a ressive allele meetsup with a dominate allele?
The genotype is said to be heterozygous and the dominant trait will be expressed in the individual.
Which animal wears a mask?
A raccoon is said to wear a mask because of its facial markings.
Is it safe to figure skate in an elaborate mask?
Depending on the mask wearers aptitude for figure skating and the visibility provided by said elaborate mask I would say its no safer than the act of figure skating with the absence of said elaborate mask.
Will there ever be another Legend of Zelda game for the 3DS?
Nintendo has said they are working on a new Zelda game, for now the game is unknown but the are rumors that the game will be majora's mask.
Describe what is occurring when a population is said to evolve?
The allele frequency of the populations gene pool is changing.
What can be said about the red and white alleles for coat color?
Red and white alleles for coat color are alternative forms of a gene that determine the color of an organism's coat. The red allele typically produces a red or orange coat color, while the white allele produces a coat color that is primarily white. The presence of these alleles, and the dominance or recessiveness of each, will determine the coat color of an individual organism.
How can you get recessive alleles together?
You need to inherit the same recessive allele from both parents. Which in turn means, that both parents need to have each have at least one copy of said recessive allele.
