what is mendel's law of Dominance? give 1 example
Answers
Answer:
Mendel's Law of Dominance states that recessive alleles will always be masked bydominant alleles. Therefore, a cross between a homozygous dominant and a homozygous recessive will always express the dominantphenotype, while still having a heterozygous genotype.
Explanation:
example:- in the pea plant, the seed color yellow always dominates seed color green. seed shape round always dominates seed shape wrinkled. So here, round (RR) and Green (GG) are the dominant traits whereas wrinkled (rr) and yellow (gg) are recessive trait.

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...''
