A student claims that dominant traits are always the most common traits. Is this true? Why or why not?(1 point)
Responses
No, dominant traits only show up if they are inherited; how common they are is not influenced by this.

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.

Yes, dominant traits are called dominant because they are the most common.
Yes, dominant traits are called dominant because they are the most common.
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 in general tend to be less common in the population and continue to persist only because they are dominant over more common recessive alleles. This is because the frequency of a trait in a population is influenced by a variety of factors, including natural selection, genetic drift, migration, and mutation. The dominance of a trait does not necessarily determine its frequency in the population.

The correct response is: No, dominant traits only show up if they are inherited; how common they are is not influenced by this.
To understand why this is the correct response, let's first clarify what dominant traits are. In genetics, traits are determined by the combination of alleles, which are different forms of a gene. Dominant traits are those that are expressed or observed in an individual if they have at least one copy of the dominant allele. On the other hand, recessive traits are only observed if an individual has two copies of the recessive allele.
It is a common misconception that dominant traits are always the most common traits. However, this is not true. The frequency of a trait in a population is not determined by its dominance or recessiveness. Instead, it is influenced by factors such as natural selection, genetic drift, and mutation rates.
Whether a dominant trait is common or not depends on the prevalence of the alleles in the population. If the dominant allele is more common in the gene pool, then the dominant trait will also be more common. Conversely, if the recessive allele is more common, then the dominant trait will be less common.
Therefore, it is incorrect to assume that dominant traits are always the most common traits. The prevalence of traits in a population is determined by a combination of genetic factors, evolutionary processes, and the interplay of different alleles in a gene pool.
