Detailed explanation-1: -When a trait is dominant, only one allele is required for the trait to be observed. A dominant allele will mask a recessive allele, if present.

Detailed explanation-2: -In general, when only one of two alleles is expressed in the phenotype, the expressed allele is called dominant, and the allele that isn’t expressed is called recessive. The terms dominant and recessive may also be used to refer to phenotypic traits. For example, purple flower color in pea plants is a dominant trait.

Detailed explanation-3: -Codominance Codominance, as it relates to genetics, refers to a type of inheritance in which two versions (alleles) of the same gene are expressed separately to yield different traits in an individual.

Detailed explanation-4: -A recessive allele is one whose effect is masked if a dominant allele is also present. males and females (one allele from each parent). The most common allele for any trait is always the dominant allele.

Detailed explanation-5: -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.
