∙ 15y agoAn allele that is always phenotypically expressed whenever present in the genome is a dominant allele. However, if the gene is inhibited or switched off by act of another gene, even the dominant allele will not be expressed, or its expression modified.

If a trait made an organism less likely to survive and reproduce what would happen to the allele for the trait?
The allele would not be passed on to further generations, as the organism cannot reproduce. There would be a smaller population of that organism who's genetic code does not contain the allele for that particular trait.
What allele whose trait only shows up when no dominant allele is present?
Such a trait is called a recessive trait.
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.
What is an example of a different form a gene may have for a trait?
The different forms of a genes for a single trait are known as alleles there can be a dominate allele which always shows up when present and a recessive allele which only shows up when both alleles are recessive or there is no dominate allele
What is the result when a dominant allele pairs up with a recessive allele in simple dominance?
The dominant form of the trait shows. -Gradpoint
What are dominant alleles?
Is one whose trait always shows up in the organism when the allele is present
Which is the dominant allele?
The dominant allele is the trait that shows up in the organism when the allele is present
Are Recessive traits always shown in an organism's offspring?
No, a recessive trait will only show in the offspring if there is no dominant allele masking it. The trait that will always show in the offspring is the dominant allele, provided one parent was homozygous for it.
Are recessive traits are always shown in an organism offspring?
No, a recessive trait will only show in the offspring if there is no dominant allele masking it. The trait that will always show in the offspring is the dominant allele, provided one parent was homozygous for it.
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.
Is an organism with a recessive allele for a particular form of a trait will always exhibit that form true or false?
false
If a trait made an organism less likely to survive and reproduce what would happen to the allele for the trait?
The allele would not be passed on to further generations, as the organism cannot reproduce. There would be a smaller population of that organism who's genetic code does not contain the allele for that particular trait.
What allele whose trait only shows up when no dominant allele is present?
Such a trait is called a recessive trait.
How can an organism have two different alleles for one trait but show one observable trait?
One allele would be dominant and the second allele would be recessive, so the organism would show only the dominant trait.
Why is it that a person with an allele for a particular trait may not have a phenotype that shows the trait?
a dominant allele will express its trait , as well as be carried by the person. the word carrier is commonly used for a person who bears an allele which does not express itself(i.e. a recessive gene).
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
