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?
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.
What type of allele is masked when a dominant allele is present?
The recessive allele is masked when a dominant allele is present. Dominant alleles are expressed over recessive alleles in heterozygous individuals.
What is dominant recessive?
There is dominant and there is recessive. There is no dominant recessive. A dominant gene will always be expressed when present, such as in the homozygous dominant genotype (RR), or heterozygous genotype (Rr). A recessive allele is only expressed when the genotype is homozygous recessive (rr).
What does dominate mean in DNA?
A dominant allele is one that will always be expressed when present.
Does recessive allele is expressed if there is no dominant allele present?
Yes, a recessive allele will be expressed if there is no dominant allele present in the genotype. This is because in the absence of a dominant allele, the recessive allele has the opportunity to be expressed in the phenotype.
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 the term for an allele that is not expressed in the phenotype of a heterozygous individual?
incomplete dominance source: PH Bio textbook
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.
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 does a dominant allele does this to another allele?
A dominant allele will mask the expression of a recessive allele when they are present together in an organism. The dominant allele will be expressed, while the recessive allele will not be visibly expressed in the organism's phenotype.
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
