Correct answer: Law of dominance
According to Mendel's law of dominance when a cross is done among the parents that are true for contrasting traits, then in such a situation only one of the trait will be shown in the next generation, and the other will be hidden. It will appear in the trait that is dominant.
The alleles that are expressed in the population are called as dominant while the trait that does not express is called a recessive trait.
