The trait that first appears or is visibly expressed in the in order to understand the concept of dominant and recessive traits it is necessary to know what is meant by the word allele. Dominant traits will not skip a generation. However recessive traits are those that are expressed only when two copies of an allele are present in the gene.
As I said above people have two versions of each gene so you can be BB Bb or bbBB and Bb have brown eyes bb blue eyes. Dominant traits will not skip a generation. Alleles have to do.
Dominant genes are usually the ones that are oftentimes observed in an offspring and passed down. Dominant traits are those traits which are expressed even in the presence of one copy of an allele for a particular trait in the gene. Dominant traits are always expressed when the connected allele is dominant even if only one copy of the dominant trait exists.
Dominant and Recessive Alleles Your genes determine characteristics or traits such as skin eye or hair color. Determine whether the trait is dominant or recessive. Recessive traits are expressed only if both the connected alleles are recessive.

Here the non-functional allele is said to be dominant because heterozygous phenotype resembles the phenotype of homozygous non-functional allele where no protein is synthesized since the functional allele is completely haploinsufficient unable to produce enough protein in.
Genes are expressed in the form of traits in living organisms.
