Question

state and explain the law of dominance with suitable example

Answer 1

In a cross of parents that are pure for contrasting traits, only one form of the trait will appear in the next generation. Offspring that are hybrid for a trait will have only the dominant trait in the phenotype 
eg in pea plants if TT is the trait for tallness ans tt for dwarfness then TT being the dominant trait will be expressed and the plant will be tall
