Jun 8, 2024 · An allele whose characteristic phenotype is masked by the presence of a second allele is called recessive when used in reference to that second allele.

Aug 9, 2023 · Recessive genes are only expressed when an individual carries two copies of the recessive allele. When a dominant allele is present, it will be expressed instead of the recessive allele.

Jun 15, 2024 · The allele that is dominant will determine the phenotype. When one allele for a particular trait masks or overrides another allele for a trait, it is called dominance.

Jun 17, 2024 · When an individual has two copies of a dominant allele, they will display the dominant trait associated with that allele. Dominant alleles mask the expression of recessive alleles in a gene …

Jan 19, 2025 · How can one determine whether a genotype is heterozygous or homozygous? One can determine whether a genotype is heterozygous or homozygous by looking at the alleles present. If …

Feb 6, 2025 · In gel electrophoresis, homozygous individuals show a single band pattern, indicating that they have two identical alleles for a particular gene. Heterozygous individuals, on the other hand, …

Jun 8, 2024 · A recessive allele is only expressed when the genotype is homozygous recessive (rr). Yes, a recessive allele will be expressed if there is no dominant allele present in the genotype.

Dec 4, 2024 · A dominant allele is called dominant because its effects will be expressed in the phenotype when present in the genotype, regardless of whether the individual has one or two copies …

Jun 14, 2024 · An allele that always shows up in an organism's phenotype and masks the expression of another allele is called dominant. Dominant alleles are always expressed, even when paired with a …

Jun 22, 2024 · A dominant allele is a form of gene that masks the presence of a recessive allele when both are present in an individual. This means that the trait associated with the dominant allele will be ...
