Hint: Mendel developed the law of inheritance. The law of dominance or inheritance states that whenever the dominant allele is present, as well as dominant allele will express itself. The expression of the recessive allele is suppressed in the presence of the dominant allele. The recessive allele does not get lost. The expression remains masked in the progeny of generation along with re-appears in the coming generation.
Complete answer:
Mendel’s law of dominance states that a dominant allele shows itself in a monohybrid cross as well as suppresses the expression of recessive allele. However, there is a recessive allele for a character that is not lost along with it remains hidden or masked in the progeny of generation as well as its reappears in the next generation.
The Law of Dominance is also known as Law of Segregation as well as Law of Independent. In this there are assortment are the three Mendel’s laws of inheritance. These laws came into life by the experiments on pea plants in a variety of differing traits. Mendel started his research with monohybrid cross.
During the experiment Mendel observed that the traits which were absent in the generation had reappeared in the generation or the next generation. These observations led to the formulation of the Law of Dominance along with the Law of Segregation.
For example, when pea plants with round seeds that are referred as (RR) are crossed with plants with wrinkled seeds described as (rr), all seeds in F generation were found to be round (Rr). When these round seeds were self-fertilised, both the round as well as wrinkled seeds appeared in generation in the ratio of 3: 1.
