Recessive alleles may not be expressed because they are?
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 the difference between dominant and recessive alleles for specific traits?
Dominant is an allele that will always be expressed in a heterozygous individual. Recessive on other hand are traits that will only be expressed in a homozygous condition. Organisms receive one allele for each trait from each parent, thus you have two alleles for each trait.
What is the type of allele that only effect the phenotype in the homozygous chromosome?
Recessive. Dominant alleles are expressed in both homozygous and heterozygous individuals (DD or Dd), but recessive alleles are only expressed in homozygous individuals (dd).
What is the difference between a dominant and recessive allele?
Dominant is an allele that can be expressed in a heterozygous individual (ie. Bb) or homozygous dominant (ie. BB). Recessive on other hand are traits that will only be expressed in a homozygous recessive (ie. bb) condition. Under normal circumstances, dominant alleles are the ones expressed in the phenotype, while the recessive allele is not. For example (an extremely simplified example) an heterozygous individual for eye color. (genotype Bb), has one dominant allele, 'B', and one recessive allele, 'b'. Given that B is for brown eyes, and b is for blue eyes, that individual's phenotype would be expressed as brown eyes (and be recessive for blue eyes). Organisms receive one allele for each trait from each parent, thus you have two alleles for each trait.
Where are the effects o f a dominant allele seen?
it is present (shown) whenever it is present ( see Punnett Square) it will overthrow a recessive allele as long as it is there. it's effect is that you will get a certain trait for that allele. A Punnett Squar will help you the most.
What allele is expressed in a heterozygote?
The allele not expressed is referred to as a recessiveallele.
What is the term for an allele that is not expressed in the phenotype of a heterozygous individual?
incomplete dominance source: PH Bio textbook
Describes the allele that is fully expressed when carried by only one of a pair of homologous chromosomes?
ecodominance
What is the difference between an inactive allele and an expressed allele?
The inactive allele is invisible in an organism while an expressed allele is the dominant allele and therefor is the phenotype.
Does a recessive allele need another recessive allele to be expressed?
I think if an allele "want" to be expressed, then it has to have a dominant allele. They don't need another recessive allele.
What Dominant alleles are both fully expressed in a phenotype?
The form of inheritance in which two (different) alleles are both expressed is called codominance. An example of codominance is the orange and black coat of a type of calico cat called a tortoiseshell. Both the orange allele and the black allele for coat color are expressed.
Allele that is always expressed if present?
An allele that is always expressed when it is present is the dominant allele.
What is an expressed allele in a heterozygote?
Dominant allele as opposed to recessive allele.
Does recessive allele is expressed if there is no dominant allele present?
YES
What are the circumstances under which dominant alleles will be expressed?
A dominant allele will be expressed when an allele pair is homozygous or heterozygous dominant.
What in term of applied to the trait that is expressed irregardless of the second allele?
The term applied to the trait that is expressed in regardless of the second allele is dominant. In contrast, the term recessive refers to a trait that is expressed when the second allele is identical.
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
