A student claims that dominant traits are always the most common traits. Is this true? Why or why not?
(1 point)
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 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.
No, dominant traits are not always the most common traits. Dominant traits can be less common in the population and still persist because they are able to mask the presence of recessive alleles. The frequency of traits in a population is influenced by various factors such as genetic drift, mutation, migration, and natural selection, rather than simply being determined by whether they are dominant or recessive. Therefore, the claim that dominant traits are always the most common is not true.
No, dominant traits are not always the most common traits. Dominant traits are called dominant because they are expressed in individuals who have at least one copy of the dominant allele. However, the frequency of dominant alleles in a population does not necessarily make them the most common traits. In fact, dominant traits can be less common in a population as compared to recessive traits. The persistence of dominant traits in a population is dependent on the fact that they are dominant over more common recessive alleles. Therefore, the claim that dominant traits are always the most common traits is not true.
No, dominant traits are not always the most common traits. Dominant traits are called dominant because they mask the expression of recessive traits in individuals who carry both dominant and recessive alleles for a particular trait. However, the frequency of dominant traits in a population is not necessarily correlated with their dominance.
In reality, the prevalence of a specific trait in a population is determined by various factors such as natural selection, genetic drift, gene flow, and mutation rates. Dominant traits can be less common in a population if they confer a selective disadvantage or if the underlying allele has a low mutation rate. On the other hand, recessive traits can also be less common if they are deleterious or if they experience selection against them.
To determine the truth of the claim, one would need to analyze the specific dominant traits in question and consider their frequencies in the population. It is important to note that the dominance of a trait does not necessarily dictate its commonness.
