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 aleles
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 intended, how common they are is not influenced by this
The correct answer is: No, dominant traits are not always the most common traits. Dominant traits can be less common in the population because they are dominant over recessive alleles that may be more common.
The answer would be: No, dominant traits are not always the most common traits. 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 correct answer is no, dominant traits are not always the most common traits. This is because the frequency of a trait in a population is not solely determined by whether it is dominant or recessive.
To explain why, we need to understand the concept of dominance and recessiveness 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.
The frequency of a trait in a population depends on the frequency of the alleles that determine that trait. If a particular dominant allele is less common in the population, then the dominant trait associated with that allele will also be less common. On the other hand, if a recessive allele is more common in the population, then the recessive trait associated with that allele may be more common.
Additionally, the concept of dominance does not determine how common a trait is overall. It only dictates how the trait is expressed in individuals with different combinations of alleles. Dominant traits can arise from rare alleles, while recessive traits can arise from more common alleles.
Therefore, while dominant traits may be more visible in individuals because they are expressed in the presence of a single copy of the allele, they are not necessarily the most common traits in a population. The frequency of a trait depends on the underlying allele frequencies in the population and the inheritance patterns involved.
