In genetics, a gene is a specific sequence of DNA that determines a particular trait. An allele is a variant form of a gene that can result in different expressions of that trait. Genes can have multiple alleles, which contribute to genetic diversity and variation in traits among individuals.
No, an allele is not considered a genotype in genetics. An allele is a specific form of a gene, while a genotype refers to the combination of alleles an individual has for a particular gene.
An allele is a specific version of a gene, while a genotype refers to the combination of alleles that an individual has for a particular gene. In simpler terms, an allele is like a variation of a gene, and a genotype is the specific genetic makeup of an individual for that gene.
An allele is a variant form of a gene that can result in different traits or characteristics in an organism. In the context of genetics, an allele is best defined as one of the possible versions of a gene that can be inherited from each parent.
An allele is a specific version of a gene that determines a particular trait or characteristic in an organism. It is one of the alternative forms of a gene that can occupy a specific position on a chromosome.
No, an allele is a variant form of a gene that determines a specific trait in an organism. It is a biological term related to genetics and has no association with a Christian band.

In genetics, dominance refers to the relationship between alleles, where one allele masks or suppresses the expression of another allele at the same gene locus. The dominant allele's traits are expressed in the phenotype, while the recessive allele's traits are hidden unless two copies are present. This concept is crucial in understanding inheritance patterns and phenotypic variations in organisms.

The comparison between the number of copies of a particular allele and the total number of copies of a gene is referred to as allele frequency. Allele frequency represents how common an allele is in a population, expressed as a proportion or percentage of the total gene copies for that gene. It is a key concept in population genetics, helping to understand genetic diversity and evolutionary dynamics within a population.
an allele is a gene that is the cause of hereditary variation
The term for the comparison between the number of copies of a particular allele and the total number of copies of that gene in a population is called "allele frequency." This measurement indicates how common an allele is relative to other alleles for that gene within a given population. It is a crucial concept in population genetics and helps researchers understand genetic diversity and evolutionary dynamics.
In a heterozygous organism, one gene may be dominant while the other is recessive. The dominant gene expresses its trait, overshadowing the effect of the recessive gene, which does not manifest in the organism's phenotype. This relationship is a fundamental principle of Mendelian genetics, where the dominant allele can mask the presence of the recessive allele in a heterozygous pairing.

The different forms of a gene are called alleles. In Mendelian genetics, a gene has a dominant allele and a recessive allele. The dominant allele masks the recessive allele if present. So there are two possible dominant genotypes: homozygous dominant, in which both dominant alleles are present; and heterozygous, in which one allele is dominant and the other allele is recessive. The only way to express a recessive trait is to have the homozygous recessive genotype.
An allele that overpowers the effect of a second form of the same gene is called a dominant allele. When a dominant allele is present, its traits are expressed in the organism, masking the effects of the recessive allele, which only shows its traits when two copies are present. This relationship is fundamental to Mendelian genetics and helps explain how traits are inherited.
The frequency of an allele in a gene pool is determined by counting the number of copies of that allele in a population. This frequency can change through evolutionary processes such as genetic drift, natural selection, mutation, and gene flow. Tracking allele frequencies helps scientists study population genetics and evolutionary dynamics.
