True or False In heterozygous individuals only the recessive allele is expressed?
In heterozygous individuals, only the dominant allele is expressed. The recessive allele is present, but not expressed
What is an allele whose trait always shows up in the organism?
type 2 Diabetes
Which form of gene pair is expressed when both dominant and recessive are present?
If the gene is governed by a dominant and recessive allele, then if the dominant allele is present, the dominant trait will be expressed. If both alleles are recessive, then the recessive trait will be expressed.
According to the rule of dominance if two different alleles are present is the dominant allele expressed?
the dominant allele is expressed when two (assuming you mean dominant and recessive) alleles are present. however, if the alleles are codominant they are both expressed.
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.
What does dominate mean in DNA?
A dominant allele is one that will always be expressed when present.
True or False In heterozygous individuals only the recessive allele is expressed?
In heterozygous individuals, only the dominant allele is expressed. The recessive allele is present, but not expressed
What is an allele whose trait always shows up in the organism?
type 2 Diabetes
Does recessive allele is expressed if there is no dominant allele present?
YES
What is the term for an allele that is not expressed in the phenotype of a heterozygous individual?
incomplete dominance source: PH Bio textbook
If an allele for a particular trait is NOT expressed at all when another allele for the trait is present the allele is .?
The allele not expressed would be recessive whilst the other is dominant. This would be the case in a heterozygous genotype. Hope this helps
What is a dominent allele?
A dominant allele is an allele that can take over a recessive allele, so if you have a dominant allele and a recessive allele, then the offspring will most likely have a dominant allele over a recessive allele. The dominant allele is expressed over the recessive allele.
Which form of gene pair is expressed when both dominant and recessive are present?
If the gene is governed by a dominant and recessive allele, then if the dominant allele is present, the dominant trait will be expressed. If both alleles are recessive, then the recessive trait will be expressed.
If an allele for a particular trait is not expressed at all when another allele for the trait is present the allele is?
The allele not expressed would be recessive whilst the other is dominant. This would be the case in a heterozygous genotype. Hope this helps
According to the rule of dominance if two different alleles are present is the dominant allele expressed?
the dominant allele is expressed when two (assuming you mean dominant and recessive) alleles are present. however, if the alleles are codominant they are both expressed.
What is the term for dominance in which the dominant allele is always expressed?
Complete dominance
What happens when 2 different allele s for the same trait are present?
if the two alleles are the same in the same box in the punnett square then that trait is expressed. when there is a double in a punnett square then that gene is always expressed
