law of dominance full answer but short
Answers
Explanation:
Inheritance is the acquiring of genetic characteristics or traits from parents by their offspring
The Law of Dominance, Law of Segregation and Law of Independent Assortment are the three Mendel’s laws of inheritance. These laws came into existence by the experiments on pea plants in a variety of differing traits. Mendel started his research with monohybrid cross.
Mendel observed that traits which were absent in the F1 generation had reappeared in the F2 generation. These observations led to the formulation of the Law of Dominance and the Law of Segregation.
✨ :-
Mendel's postulate of dominance was raised to the status of Law of Dominance by Correns . The statements are :-
- Characters are controlled by discrete units called factors.
- Factors occur in pairs.
- In a dissimilar pair of factors , one member of the pair dominates the other.
- In a hybrid, dominant allele express itself while a recessive allele is unable to express.
The law of dominance is used to explain the expression of only one of the parental characters in a monohybrid cross in the F and the expression of both in the F .
It also explains the proportion of 3:1 obtained at the F.
