Detailed explanation-1: -This is also called Mendel’s first law of inheritance. According to the law of dominance, hybrid offspring will only inherit the dominant trait in the phenotype. The alleles that are suppressed are called the recessive traits while the alleles that determine the trait are known as the dominant traits.
Detailed explanation-2: -Mendel’s law of dominance states that: “When parents with pure, contrasting traits are crossed together, only one form of trait appears in the next generation. The hybrid offsprings will exhibit only the dominant trait in the phenotype.” Law of dominance is known as the first law of inheritance.
Detailed explanation-3: -Mendel has clearly stated in his results that each individual has two factors for each trait, one from each parent. The factor which is dominant, its trait gets expressed. The two factors present in an individual may or may not be the same.
Detailed explanation-4: -Mendel’s studies yielded three “laws” of inheritance: the law of dominance, the law of segregation, and the law of independent assortment. Each of these can be understood through examining the process of meiosis.
