What the 2 alleles are that control a specific characteristic?
The two alleles that control a specific characteristic are typically referred to as the dominant allele and the recessive allele. The dominant allele is expressed in the phenotype when present with a recessive allele, while the recessive allele is only expressed when two copies are present.
How many recessive alleles are needed to be expressed?
Depends on the characteristic. Assuming you're talking about a very simple monogenic characteristic (ie. a characteristic which is dependent on one gene only) your dominant allele will always trump your recessive allele. So, one copy of your dominant allele is all that's needed to give you that characteristic (final genotype is either homozygous dominant or heterozygous), whereas you'd need two copies of your recessive allele (homozygous recessive) to get that characteristic. Much beyond that and it gets verycomplicated.
How is a recessive allele from a dominant allele?
its different because adominant allele is in charge
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.
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 the 2 alleles are that control a specific characteristic?
The two alleles that control a specific characteristic are typically referred to as the dominant allele and the recessive allele. The dominant allele is expressed in the phenotype when present with a recessive allele, while the recessive allele is only expressed when two copies are present.
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
Differences between dominant and recessive?
Dominant is stronger than recessive. So you can only have the phenotype ( visual characteristic ) of a recessive allele if you have 2 recessive alleles in your DNA , and other combination the dominant allele would be predominant
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).
Describes a trait or an allele that is expressed only when two of the alleles for the saame characteristic are inherited?
A trait or allele that is only expressed when two alleles of the same type are inherited is called recessive. This means that the individual must inherit two copies of the recessive allele to exhibit the trait. If an individual inherits one dominant allele and one recessive allele for a trait, the dominant allele will be expressed.
How many recessive alleles are needed to be expressed?
Depends on the characteristic. Assuming you're talking about a very simple monogenic characteristic (ie. a characteristic which is dependent on one gene only) your dominant allele will always trump your recessive allele.

What allele whose trait only shows up when no dominant allele is present?
Such a trait is called a recessive trait.
Is an allele that produces a trait in the heterozygous condition 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.
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 tessesive trait?
In genetics, a recessive trait is a characteristic that is only expressed when an individual has two copies of the recessive allele. This means that an individual must inherit two copies of the specific allele (one from each parent) in order for the recessive trait to be visibly manifested in the phenotype.
