One allele can alter another allele through a process called epistasis, where the expression of one gene masks or modifies the expression of another gene at a different locus. This interaction can affect phenotypic traits, leading to variations in how traits are expressed. Additionally, certain alleles may exhibit dominance or recessiveness, where the dominant allele's effects overshadow those of the recessive allele. Overall, the interplay between alleles can significantly influence an organism's characteristics.
What else can I help you with?
Does a recessive allele need another recessive allele to be expressed?
Yes, a recessive allele needs to be paired with another recessive allele in order to be expressed. This is because recessive alleles are only expressed when an individual has two copies of the recessive allele, one from each parent. If an individual has one dominant allele and one recessive allele for a particular trait, the dominant allele will be expressed.
What is a Reciessive form of an allele?
A recessive form of an allele is one that is only expressed in the presence of another recessive allele.
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 one allele shows dominance over another allele?
In cases of complete dominance, one allele, known as the dominant allele, masks the expression of the other allele, known as the recessive allele, in the heterozygous state. This results in only the dominant allele being expressed in the phenotype.
When 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.

This is because recessive alleles are only expressed when an individual has two copies of the recessive allele, one from each parent. If an individual has one dominant allele and one recessive allele for a particular trait, the dominant allele will be expressed.
How are the bases in one allele different from the bases in another allele?
The bases in one allele is different from bases in another allele because an allele is different forms of the same gene. This means that even though they have been programed for the same thing there is a variation
Is when one allele completely masks another?
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.
What is a Reciessive form of an allele?
A recessive form of an allele is one that is only expressed in the presence of another recessive allele.

What is the name given to an allele that masks another?
A dominant one
What is it called in situations in which one allele for a gene is not completely dominant over another allele for that gene?
incomplete dominance
What is the nature of a relationship in which one allele is completely dominant over another in genetic inheritance?
In a relationship where one allele is completely dominant over another in genetic inheritance, the dominant allele will always be expressed in the phenotype, while the recessive allele will only be expressed if both alleles are recessive. This is known as complete dominance.
