Detailed explanation-1: -The dominance or recessivity associated with a particular allele is the result of masking, by which a dominant phenotype hides a recessive phenotype. By this logic, in heterozygous offspring only the dominant phenotype will be apparent.

Detailed explanation-2: -A dominant allele produces a dominant phenotype in individuals who have one copy of the allele, which can come from just one parent. For a recessive allele to produce a recessive phenotype, the individual must have two copies, one from each parent.

Detailed explanation-3: -“A person with a dominant personality type is assertive, courageous, proactive, and self-reliant, ” she says. “They are focused and goal-oriented as well. These individuals carry themselves in a manner that is socially impressive and emanates positive vibes to others.”

Detailed explanation-4: -An organism receives two genes for each trait, one from each parent. One of the genes may be stronger; the trait of the stronger gene shows up and is called the dominant gene. The trait of the weaker gene is “hidden” or does not show up and is called the recessive gene.
