A recessive allele is hidden whenever the dominant allele is present. It can only be seen when it is paired up with another recessive allele.
What is hidden whenever the dominant allele is present?
A dominant allele is one whose trait always shows up in the organism when the allele is present. A recessive allele is hidden whenever the dominant allele is present.
Can a dominant allele be hidden?
One allele for every gene in an organism is inherited from each of that organism’s parents. … The dominance or recessivity associated with a particular allele is the result of masking, by which a dominant phenotype hides a recessive phenotype.
What is the hidden allele called?
6th grade Chapter 4 Science Review
|an allele that can be masked, or hidden, by tht presence of another allele is classified as||recessive|
|both alleles influence the phenotype, causing a blended appearance||incomplete dominance|
|an organism that has two different alleles for a particular trait||hybrid|
What is a trait that is hidden by a dominant trait?
recessive allele. A trait that is hidden when the dominant allele is present. hybrid. An organism that has two different alleles for a trait (Tt)
What happens to the recessive allele when a dominant allele is present?
Your genotype for a specific gene determines what the physical appearance, or phenotype, of that feature will be. If both of the alleles you inherited from your parents are the same, the genotype is homozygous. However, if you have one dominant and one recessive allele, the genotype is heterozygous.
How can a dominant allele be rare?
Rare Dominant Genes
Some dominant genes are rare, meaning that a small subset of humans have the dominant allele. The polydactyly trait — having extra fingers or toes — is one example of a rare inherited dominant gene trait.
How do you know if you have dominant or recessive genes?
Dominant alleles are seen as an uppercase of a letter; for example, B. Recessive alleles are seen as a lower case of a letter; b. In order for a person to show the dominant trait, one of the person’s parents must have the dominant trait (which is an uppercase letter).
When a dominant allele is present the offspring will show what type of characteristics?
When a dominant allele is present it will show itself. A recessive allele will only show itself when there are two.
