A student claims that dominant traits are always the most common traits. Is this true? Why or why not?(1 point)
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 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 in general tend to be less common in the population and continue to persist only because they are dominant over more common recessive alleles. The frequency of a trait in a population is not determined solely by its dominance or recessiveness. Various factors, such as genetic drift, migration, and natural selection, can influence the prevalence of different traits in a population. Therefore, dominant traits are not always the most common traits.
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 means that even though dominant traits may be expressed in individuals who have inherited them, they are not necessarily the most common traits overall. The frequency of dominant and recessive traits in a population depends on factors such as the size of the population, the gene flow, and natural selection. Therefore, it is not accurate to say that dominant traits are always the most common traits.
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.
Dominance refers to the relationship between alleles, which are different forms of a gene. Dominant alleles are expressed when present in an individual's genotype, meaning they determine the observed trait. Recessive alleles, on the other hand, are only expressed if there are no dominant alleles present.
The frequency of dominant traits in a population is not necessarily related to their dominance. Dominant traits can be less common than recessive traits for several reasons. First, the number of possible dominant traits is limited as they require at least one dominant allele to be expressed. In contrast, recessive traits can be masked and remain hidden in carriers who do not visibly display the trait. This allows for a wider range of possible recessive traits.
Additionally, the frequency of different traits in a population is influenced by factors such as natural selection, genetic drift, and migration. These factors can impact the frequency of both dominant and recessive traits, making it difficult to generalize that dominant traits are always the most common.
To determine the prevalence of a particular trait in a population, one would need to study the frequency of both dominant and recessive alleles and how they are inherited over multiple generations.
