A student claims that dominant traits are always the most common traits. is this true

No, this claim is not true. Dominant traits are genetic traits that are expressed or visible in an individual, while recessive traits are only expressed when an individual inherits two copies of the recessive allele. The occurrence of dominant and recessive traits in a population depends on the specific alleles or genes being considered and their frequency within the gene pool. In some cases, dominant traits can be more common in a population, but this is not always the case. The frequency of traits in a population is influenced by various factors including genetic variation, natural selection, and random chance. Therefore, it cannot be generalized that dominant traits are always the most common traits.
