When Mendel experimented with pea plants, he found that one trait appeared more often than another trait. Which of the following BEST describes Mendel's Law of Dominance?

Question

When an organism has two different alleles present for a trait, the recessive trait will not be expressed.
When an organism has two different alleles present for a trait, both traits will be equally expressed.
When an organism has two of the same alleles for a trait, the stronger will be expressed in the organism.
When an organism has two of the same alleles for a trait, that trait is not expressed.

Answer 1

The statement that BEST describes Mendel's Law of Dominance is: When an organism has two different alleles present for a trait, the recessive trait will not be expressed.

This aligns with Mendel's findings that in a pair of contrasting traits, the dominant allele will mask the effect of the recessive allele when both are present.
