Yes, a recessive allele is only expressed when an individual has two copies of that allele (homozygous recessive) or when the dominant allele is absent. It is "hidden" in the presence of a dominant allele.
a resscessive allele, is hidden when the dominant trait is present
The building blocks of our genes (that make us what we are) are called alleles and these can be either dominant, recessive or codominant - which means they are equally dominant. Now for your sentence: "A typical example of codominance can be found in blood types, where the existence of A as well as B alleles in a person will lead to blood type AB".
i think the answer your lokking for is recessive Recessive is when you have a trait in your genome but it doesn't show in your physical appearance

The hidden or masked form of a gene is called recessive. 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.
In a heterozygote, there are two different alleles for a specific gene. One allele is dominant and will be expressed, while the other allele, called the recessive allele, is not expressed but is still present in the genetic makeup of the individual. The recessive allele is "hidden" in the heterozygote because its presence does not affect the outward appearance or expression of the dominant allele.
Genes that are hidden when paired with a different allele in genetics are called recessive genes.
If you mean allele, then the answer is a recessive allele. A recessive allele is dominated by a dominant allele, and generally does not show up physically.
In a heterozygous offspring, the recessive allele is present, but it is overridden by the dominant allele in terms of physical expression. The recessive allele still remains in the genetic makeup of the offspring and can be passed on to future generations.
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.
Heterozygotes have two different alleles for a particular gene, where one allele is dominant and the other is recessive. The recessive allele is "hidden" in heterozygotes because it is not expressed phenotypically but can be passed on to offspring.
