Description : When one gene pair hides the effect of the other unit, the phenomenon is referred to as: (1) Epistasis (2) Mutation (3) None of the options (4) Dominance
Last Answer : (1) Epistasis Explanation: Epistasis refers to the phenomenon in which one gene hides the effect of the other. In other word, it does not allow the other gene to express itself. This is counterpart of ... may be in one direction only meaning that ei-ther A hides the effect of B or vice versa.

Description : What is the difference between a dominant and recessive trait?
Last Answer : A: A dominant trait is a genetic trait that is expressed when present in either one or both copies of the gene, while a recessive trait is a genetic trait that is only expressed when present in both copies of the gene.
Description : What is the difference between a dominant and recessive allele?
Last Answer : A: A dominant allele expresses its phenotype even if only one copy is present, while a recessive allele expresses its phenotype only if two copies are present.
Description : What is the difference between dominant and recessive traits?
Last Answer : A: Dominant traits are expressed when a person has one copy of a dominant allele, while recessive traits are expressed only when a person has two copies of a recessive allele.
Description : What is the difference between a dominant and a recessive allele?
Last Answer : A: A dominant allele is one that is expressed in the phenotype of an organism even if only one copy is present, while a recessive allele is only expressed in the phenotype if two copies are present.
Description : What is the difference between a recessive and a dominant allele?
Last Answer : A: A recessive allele is an allele that is only expressed when present in a homozygous state, while a dominant allele is an allele that is expressed even when present in a heterozygous state.
Last Answer : A: A dominant allele is expressed in the phenotype when present, while a recessive allele is only expressed in the phenotype when two copies are present.
Last Answer : A: A dominant allele is expressed in the phenotype even if it is present in only one copy, while a recessive allele is only expressed in the phenotype if it is present in two copies.
Description : What is the difference between a dominant allele and a recessive allele?
Last Answer : A: A dominant allele is expressed when present in either the homozygous or heterozygous state, while a recessive allele is only expressed when present in the homozygous state.
Description : What is the difference between a dominant and a recessive trait?
Last Answer : A: A dominant trait is expressed when an individual has one or two copies of the dominant allele, while a recessive trait is expressed only when an individual has two copies of the recessive allele.
Last Answer : A: A dominant allele masks the expression of a recessive allele in a heterozygous individual.
Description : f we cross pure-bred tall (dominant) pea plant with pure-bred dwarf (recessive) pea plant we will get pea plants of F1 generation.
