Will an organism with a recessive allele for a particular form of a trait will always exhibit that form?

Only when both genes in the pair are homozygous recessive, the expression will be masked, otherwise, if only one gene of the allelic pair is recessive and the other one is dominant, the expression of dominant gene will be apparent.

∙ 11y agoif a dominant trait is not damaged the recessive trait will not be evident so an organism with a dominant trait will always exhibit that trait unless certain circumstance are evident

∙ 12y agoan organism with recessive allele for a particular form of a trait may not always exhibit that form. ie.---- FALSE----

Wiki User
∙ 12y agoIf an offspring has only alleles for the recessive trait, which is referred to as being homozygous recessive, than the recessive trait must be expressed.

Why is it not necessary when the dominant and recessive traits are known to use the term homozygous when referring to the genotype of an individual that has a recessive phenotype?
An organism with a recessive allele from a particular form of a trait will exhibit that form only when the dominant allele for the trait is not present.
Which trait will a male exhibit if he carries a recessive allele on the X chromosome?
A male carrying a recessive allele on the X chromosome will exhibit the recessive trait. This is because the Y chromosome generally does not have matching genes for the X chromosome, unlike the other 22 pairs if chromosomes in the nucleus.
What is allele masked by the dominant allele?
The Allele That Is Covered By The Dominant Allele Is The Recessive Allele.
Is when one allele completely masks another?
when one allele is completely dominant over another allele, then it masks the expression of the second allele so the allele that masks the effect is called dominant allele and the allele whos effect is masked is called recessive allele
What is a genotype with one dominant and one recessive gene?
The genotype of a person with one dominate allele for a gene and one recessive would be expressed as Aa or Yy. You can use any letter you would like except one will be shown as a capital (dominate) and one as a lower case (recessive). This combination is heterozygous for that trait.
Is an organism with a recessive allele for a particular form of a trait will always exhibit that form true or false?
false

An organism with a recessive allele from a particular form of a trait will exhibit that form only when the dominant allele for the trait is not present.
An organism carrying one dominant and one recessive allele for a particular trait would be what?
Heterozyous
An organism carrying one dominant and one recessive allele for particular trait would be for that trait?
Heterozygous.
When an organism is carrying one dominant and one recessive allele for a particular trait what would be that trait?
Heterozygous
An organism carrying one dominant and dominant and one recessive allele for a particular trait would be what for that trait?
Heterozygous.
What is meant by dominance?
Complete dominance means that the dominant allele completely masks the effects of the recessive allele. The only way a recessive allele can be exhibited phenotypically is if the organism is homozygous recessive for that allele.
Some alleles are neither dominant or recessive and many traits are controlled by what?
Each person has two alleles of one particular gene, which controls one particular characteristic, such as a person's blood group. An allele may be either dominant, recessive, or codominant. A dominant allele would dominate the other allele in the chromosomes, meaning only the dominant allele would contribute to an organism's characteristics. An example of this is the A blood group, which is dominant to the O allele. However, if an individual has both A and B alleles, A and B are codominant, as they both exhibit effects on an organism's characteristics (the blood group). This results in an AB blood group - a combination of the effects of two genes!
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 dominant or recessive variant of a particular gene?
An allele
Which trait will a male exhibit if he carries a recessive allele on the X chromosome?
A male carrying a recessive allele on the X chromosome will exhibit the recessive trait. This is because the Y chromosome generally does not have matching genes for the X chromosome, unlike the other 22 pairs if chromosomes in the nucleus.
What gene will exhibit its traits even in a prensesce of a recessive gene?
The dominant allele
