What else can I help you with?
When neither allele is dominant what are they expressed as?
Both of the alleles must be recessive. The trait expressed is a recessive trait.
What allele whose trait only shows up when no dominant allele is present?
Such a trait is called a recessive trait.
What conclusion about your genotype is evident if one of your siblings but neither parent shows the recessive trait?
If one of your siblings shows the recessive trait but neither parent does, it suggests that both parents are carriers of the recessive allele. This means that you and your unaffected sibling have a 25% chance of inheriting two copies of the recessive allele, resulting in the recessive trait expression.
In a heterozygote the allele that does not affect the trait?
The allele that does not affect the trait in a heterozygote is known as the recessive allele. This allele is masked by the dominant allele, which determines the observable trait. However, the recessive allele can still be passed on to offspring if both parents are carriers.
Which allele (gene) exhibits its trait only when it is paired with another allele in a genetic cross?
Recessive allele exhibits its trait only when paired with another recessive allele in a genetic cross.
When neither allele is dominant what are they expressed as?
Both of the alleles must be recessive. The trait expressed is a recessive trait.
When neither allele is dominant (they are both expressed)?
Both of the alleles must be recessive. The trait expressed is a recessive trait.
When two alleles for one trait are present and neither allele overshadows the other is demonstrated.?
incomplete dominance
Is an inheritance pattern in which neither allele for a trait dominates the other?
Incomplete Dominance
What allele whose trait only shows up when no dominant allele is present?
Such a trait is called a recessive trait.
What carrier of a trait controlled by a allele does not express the trait?
A carrier of a trait controlled by a recessive allele possesses one copy of the recessive allele and one copy of the dominant allele. This means that they do not express the trait associated with the recessive allele because the dominant allele masks its effect. However, the carrier can pass the recessive allele to their offspring, who may express the trait if they inherit two copies of the recessive allele.
What conclusion about your genotype is evident if one of your siblings but neither parent shows the recessive trait?
If one of your siblings shows the recessive trait but neither parent does, it suggests that both parents are carriers of the recessive allele. This means that you and your unaffected sibling have a 25% chance of inheriting two copies of the recessive allele, resulting in the recessive trait expression.
In a heterozygote the allele that does not affect the trait?
The allele that does not affect the trait in a heterozygote is known as the recessive allele. This allele is masked by the dominant allele, which determines the observable trait. However, the recessive allele can still be passed on to offspring if both parents are carriers.
What is member of a gene pair that determines a specific trait is?
an allele
How does an allele trait in an organism?
An allele causes a trait by either being dominant orrecessive or example, allele A will occur over allele a because it is dominant.
An allele that is dominated or cover up by another allele is called what?
An allele that is dominated or covered up by another allele is called a recessive allele. This means that the trait associated with the recessive allele is only expressed when an individual carries two copies of that allele.
What allele does affect the trait in a heterozygote?
The recessive allele.
