Is when one allele completely masks another?

when one allele is completely dominant over another allele, then it masks the expression of the second allele so the allele that masks the effect is called dominant allele and the allele whos effect is masked is called recessive 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.


What gene won't display its trait in the prescience of a dominate trait?

The recessive form of a gene, called a recessive allele, will not be expressed in the presence of the dominant form of the gene, called a dominant allele.
