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.
When on e allele of a gene masks the presence of the other allele what form is masked?
The recessive allele.
When one of a gene masks the presence of the other allele what form is masked?
The recessive allele.
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 the term for an allele that is not expressed in the phenotype of a heterozygous individual?

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 allele masked by the dominant 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).
What is the form of a gene that is hidden or masked when any other form of that same gene is present?
The hidden or masked form of a gene is called recessive. Recessive genes are only expressed when an individual carries two copies of the recessive allele. When a dominant allele is present, it will be expressed instead of the recessive allele.
Which form of gene pair is expressed when both dominant and recessive are present?
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.
When on e allele of a gene masks the presence of the other allele what form is masked?
The recessive allele.
When one allele of a gene masks the presence of the other allele what form is masked.?
recessive A+
When one of a gene masks the presence of the other allele what form is masked?
The recessive allele.
Is albinism controlled by a dominant allele or by a recessive allele?
Recessive allele.
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 are two forms that a gene or allele may take?
A gene or allele may take a dominant form, or a recessive form. If the allele is recessive, the characteristic which is coded for will be exhibited only if both the gene from the male and the gene from the female is recessive. Only one copy of a dominant allele is required to cause expression of the dominant characteristic
What is the result when a dominant allele pairs up with a recessive allele in simple dominance?
The dominant form of the trait shows. -Gradpoint
