Question

True or False. Dominant traits are traits that will be expressed. Recessive traits are traits that are never expressed in the presence of a dominant trait. They can only be expressed when both alleles are recessive.

Answer 1

Dominant traits will be expressed, while recessive traits require both alleles to be recessive in order to be expressed.

Step-by-step explanation:

In genetics, dominant traits are traits that will be expressed in an individual's phenotype, even if they only have one copy of the dominant allele. On the other hand, recessive traits are traits that are only expressed when an individual has two copies of the recessive allele.

For example, if we consider the trait of eye color, brown eye color is a dominant trait. This means that if an individual has one copy of the allele for brown eyes and one copy of the allele for blue eyes, their phenotype will express brown eye color. Blue eye color, in this case, is a recessive trait, and it will only be expressed if the individual has two copies of the allele for blue eyes.

Therefore, the statement is true. Dominant traits will be expressed, while recessive traits require both alleles to be recessive in order to be expressed.

Answer 2

Dominant traits are traits that will be expressed. Recessive traits are traits that are never expressed in the presence of a dominant trait. They can only be expressed when both alleles are recessive.

This is true.

Dominant traits are just that - dominant. If they are present in the genotype, they will appear in the phenotype.
