Recessive
A phenotype is the whole set of the characteristic of an organism, like physical characteristics (colour of skin, presence of plumes, presence of wings), behavior (like type of nest, nutritional habits and so on). The phenotype is the result of the so called genotype (the set of inherited genetic information) and of the organism history and experience.

The phenotype is the result of the so called genotype (the set of inherited genetic information) and of the organism history and experience.
The general term for an allele that masks the presence of another allele in the phenotype is "dominant." Dominant alleles are expressed phenotypically when present, masking the effects of recessive alleles.
Dominant expression refers to the situation where a specific gene allele is more likely to be expressed in an individual, resulting in the appearance of a certain characteristic or trait. This can mask the presence of a recessive allele that carries a different trait.
Incomplete Dominance
It is called codominance or incomplete dominance.
When a heterozygous genotype (two different alleles) results in an intermediate phenotype, this is either codominance or incomplete dominance. If it is codominance, then both alleles are expressed together in the phenotype. If it is incomplete dominance, the two alleles produce a blended phenotype rather than both alleles being expressed together.
If you have a dimpled chin, your phenotype includes this specific physical trait, which is a visible characteristic resulting from your genetic makeup. The presence of a dimpled chin is often associated with a genetic variation, typically considered a dominant trait. Therefore, your phenotype reflects not just the dimpled chin, but also other observable traits you may have inherited from your parents. Overall, phenotypes encompass a range of physical features influenced by genetics and environmental factors.
Yes, both Aa and AA genotypes represent the dominant phenotype for a specific trait. The presence of at least one dominant allele (A) will result in the dominant phenotype being expressed.
One environmental factor that can affect an organism's phenotype is the presence of stress hormones like cortisol. High levels of cortisol can impact an organism's physical characteristics, behavior, and overall health, leading to changes in the phenotype.
