What is member of a gene pair that determines a specific trait is?
an allele
An allele that is dominated or cover up by another allele is called what?
An allele that is dominated or covered up by another allele is called a recessive allele. This means that the trait associated with the recessive allele is only expressed when an individual carries two copies of that allele.
What does a dominant allele always do?
A dominant allele expresses its trait in an individual when present, masking the effect of a recessive allele. This means that if an individual has at least one copy of a dominant allele, the associated trait will be displayed.
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 type of alleles does a person considered a Carrier have?
A person considered a carrier typically has one normal (dominant) allele and one mutated (recessive) allele for a specific gene. This means they do not exhibit symptoms of the genetic condition associated with the recessive allele but can pass the mutated allele to their offspring. For example, in autosomal recessive disorders, carriers are asymptomatic but can potentially have affected children if their partner is also a carrier.
Homozygous for b allele?
Being homozygous for the "b" allele means that an individual has two identical copies of the "b" allele at a specific gene locus. This implies that both alleles are the same, resulting in a specific genetic trait or characteristic associated with the "b" allele being expressed.
What is member of a gene pair that determines a specific trait is?
an allele
What is the method to calculate allele frequencies for a specific gene in a population?
To calculate allele frequencies for a specific gene in a population, you can use the formula: allele frequency (number of copies of a specific allele) / (total number of alleles in the population). This helps determine how common a particular allele is within the population.
Which allele is associated with the BRCA2 mutation?
The BRCA2 mutation is associated with a variety of mutations across its gene. However, most commonly, the mutation is found in one allele of the BRCA2 gene located on chromosome 13.
What genotype is ff?
The genotype ff represents a homozygous recessive individual for a specific gene. This means that both alleles for the gene are the same and both are the recessive allele (f). This individual will exhibit the trait associated with the recessive allele.
An allele that is dominated or cover up by another allele is called what?
An allele that is dominated or covered up by another allele is called a recessive allele. This means that the trait associated with the recessive allele is only expressed when an individual carries two copies of that allele.
What does a dominant allele always do?
A dominant allele expresses its trait in an individual when present, masking the effect of a recessive allele. This means that if an individual has at least one copy of a dominant allele, the associated trait will be displayed.
What are pairs called?
A gene pair is called an allele. An allele is an alternative form of a gene that is located on a specific chromosome at a specific place.
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.

This means they do not exhibit symptoms of the genetic condition associated with the recessive allele but can pass the mutated allele to their offspring. For example, in autosomal recessive disorders, carriers are asymptomatic but can potentially have affected children if their partner is also a carrier.
How do you know that a pea plant with wrinkled seeds does not have one copy of the round seed allele?
The trait associated with the allele is not expressed in heterozygotes.
Is an allele a trait that determines a specific characteristic in an organism?
Yes, an allele is a variant form of a gene that determines a specific characteristic or trait in an organism.
