3. A student claims that dominant traits are always the most common traits. Is this true? Why or why not? A. Yes, dominant traits are called dominant because they are the most common.

B. No, dominant traits only show up if they are inherited; how common they are is not influenced by this.

C. 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.

D. 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.

The True statement is ; ( B ) No dominant traits only show up if they are inherited ; how common they are is not influenced by this

Dominant traits are traits that are expressed in a combination of alleles ( i.e. They are the traits that overshadows recessive traits ). A trait been dominant is not directly affected by the popularity of the trait.

A dominant trait is inherited and it is directly determined by the total combination of alleles in a particular population. an example of a dominant traits is tongue rolling which is not common but is a dominant trait in certain population.

Hence we can conclude that, The True statement is No dominant traits only show up if they are inherited ; how common they are is not influenced by this.

Option B.

Explanation:

If a trait is common or not it has very little or nothing to do with if the trait is dominant or recessive but it solely depends on total copies of the allele present in that particular population.

Dominant allele does not make an allele common, dominant term only explains that it expressed itself in presence of the recessive allele. For instance, the rolling tongue is not common even though it is a dominant allele and expressed in heterozygous condition.
