A dominant allele
A dominant allele will mask the prsence of a recssive 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).
No. A recessive allele will not be expressed phenotypically in the heterozygous state. A recessive allele can only be expressed phenotypically in the homozygous state.
In a situation where both a dominant and recessive allele are present in a gene pair, the dominant allele will be expressed phenotypically. The presence of a dominant allele overrides the expression of the recessive allele.
This is called complete dominance, where one allele completely masks the expression of another allele in a heterozygous individual. The dominant allele is expressed phenotypically, while the recessive allele remains hidden.
A dominant allele will express itself if present, and will suppress the recessive allele's expression.

A dominant allele will mask the prsence of a recssive 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).
A dominant allele will mask the expression of a recessive allele when they are present together in an organism. The dominant allele will be expressed, while the recessive allele will not be visibly expressed in the organism's phenotype.
The term you're looking for is "recessive allele." A recessive allele is only expressed in an organism's phenotype when two copies are present, meaning the corresponding dominant allele is absent. In other words, for a trait associated with a recessive allele to be visible, the individual must inherit the recessive allele from both parents. If at least one dominant allele is present, it will mask the expression of the recessive allele.
No. A recessive allele will not be expressed phenotypically in the heterozygous state. A recessive allele can only be expressed phenotypically in the homozygous state.

This is called complete dominance, where one allele completely masks the expression of another allele in a heterozygous individual. The dominant allele is expressed phenotypically, while the recessive allele remains hidden.
Recessive allele.
Having a dominant and recessive allele is known as Mendelian inheritance, named after Gregor Mendel, the scientist who first described it. In this type of inheritance, the dominant allele masks the expression of the recessive allele in heterozygous individuals.
A dominant alle masks the expression of the recessive trait in a heterozygous genotype, a recessive allele is the phenotpye expressed is the recessive trait.
