A student claims that dominant traits are always the most common traits. Is this true? Why or why not?(1 point)
Responses
Yes, dominant traits are called dominant because they are the most common.

Yes, dominant traits became more common over time as they are passed down from generation to generation; recessive alleles continue to become less common over time.

No, dominant traits only show up if they are inherited; how common they are is not influenced by this.

No, dominant traits in general tend to be less common in the population and continue to persist only because they are dominant over more common recessive alleles.

No, dominant traits are not always the most common traits. Dominance refers to how a particular trait is expressed in an individual's phenotype, but it does not necessarily determine the frequency or commonness of that trait in a population.
To understand why this is the case, it is important to consider the concept of alleles. Alleles are alternate forms of a gene that can contribute to the expression of a trait. In a population, there can be multiple alleles for a particular gene, and some of these alleles may be dominant while others are recessive.
The frequency of a trait in a population is influenced by various factors such as natural selection, genetic drift, gene flow, and mutation. Dominant traits may or may not be the most common depending on these factors.
For example, let's consider a population of flowers with two alleles for a specific gene that controls flower color - a dominant allele for pink flowers and a recessive allele for white flowers. If the pink flower allele provides a selective advantage, such as attracting pollinators more effectively, then over time, the frequency of the dominant allele may increase in the population, making pink flowers the most common trait. However, if there is no selective advantage, or if the recessive allele has some other advantage, then the frequency of white flowers may be higher.
In summary, whether a dominant trait is the most common or not depends on various genetic and environmental factors. The dominance of a trait does not automatically determine its frequency in a population.
