an allele
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.
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.
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.
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.
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.
an allele
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.
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.
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 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.
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.
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.
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.
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.
Yes, an allele is a variant form of a gene that determines a specific characteristic or trait in an organism.
The trait associated with the allele is not expressed in heterozygotes.
