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 in general tend to be less common in the population and continue to persist only because they are dominant over more common recessive alleles.

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 only show up if they are inherited; how common they are is not influenced by this.

No, dominant traits are not always the most common traits. Dominance refers to the expression of a trait in the presence of another allele, not its frequency in a population. In fact, dominant traits are often less common in the population and continue to persist only because they are dominant over more common recessive alleles.
The correct answer is:
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.
Explanation of how to get the answer:
To determine if the student's claim is true or not, we need to understand the concepts of dominant and recessive traits in genetics. In genetics, dominant traits are expressed when an individual has at least one copy of the dominant allele, while recessive traits are expressed only when an individual has two copies of the recessive allele.
In general, dominant traits tend to be less common in the population compared to recessive traits. This is because recessive traits can remain hidden in individuals who are carriers (heterozygous) and not express the trait themselves. However, these carriers can pass on the recessive allele to their offspring. So, even if a trait is recessive, it can still be quite common in the population if many individuals are carriers.
Dominant traits persist in the population because they are dominant over the recessive alleles. In other words, even if the dominant allele is less common than the recessive allele, individuals carrying the dominant allele will express the trait. This means that even if a dominant trait is less common in the population, it can still appear in offspring when inherited from a parent who carries the dominant allele.
Therefore, the student's claim that dominant traits are always the most common traits is not true.
