Answers
Answer:
The Three Mendel's laws of Inheritance are:
1. The Law Of Dominance
2. The Law Of Segregation
3. The Law Of Independent Assortment
Law of segregation is universally accepted with no exception.
Explanation:
Law of segregation states that each trait is consist of two alleles, which get segregate during the formation of gametes and one allele from each parent combine during fertilization.
According to Mendel's First Law of Inheritance or The Law of Dominance, ''In the cross between two parents who differ in one genetic characteristic for which they are both homozygous, all the offsprings in the first filial generation are equal to the examined characteristic in the genotype and phenotype showing the dominant trait...''
According to Mendel's Second Law of Inheritance or The Law of Segregation, ''The characteristics or the traits of an organism are determined by internal factors which occur in pairs. Only one of a pair of such factors can be present in a single gamete...''
According to Mendel's Third Law of Inheritance or The Law of Independent Assortment, ''In the inheritance of more than one pair of traits in a cross simultaneously, the factors responsible for each pair of traits are distributed independently to the gametes...''
