What allele whose trait only shows up when no dominant allele is present?
Such a trait is called a recessive trait.
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 does the word dominant mean in genetics?
In genetics, "dominant" refers to an allele that will be expressed in the phenotype if present, masking the expression of the corresponding recessive allele. This means that even if an individual has one dominant allele and one recessive allele for a particular trait, the dominant allele's phenotype will be visible.
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.
What is an allele that produces a trait in the heterozygous condition called?
An allele that produces a trait in the heterozygous condition is called dominant. This means that only one copy of the allele is needed to express the trait.
What does 'R' and 'r' mean in chromosomes?
R is a dominant allele for trait 'r' and r is a recessive allele for trait 'r'.
What does resscessive mean?
a resscessive allele, is hidden when the dominant trait is present
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.
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.
What does the word dominant mean in genetics?
In genetics, "dominant" refers to an allele that will be expressed in the phenotype if present, masking the expression of the corresponding recessive allele. This means that even if an individual has one dominant allele and one recessive allele for a particular trait, the dominant allele's phenotype will be visible.
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.
Yy is the what of an individual?
"Yy" typically refers to a genetic code for a specific trait, where "Y" represents a dominant allele and "y" represents a recessive allele. In terms of individuals, the presence of "Yy" would mean that they have one dominant allele and one recessive allele for that particular trait.
What allele does affect the trait in a heterozygote?
The recessive allele.
What allele for the sickle cell trait is with the normal allele?
codominant
