FAQs on Dominant & Recessive Traits Video Lecture - NEET

1. What are dominant and recessive traits?

Ans. Dominant and recessive traits are terms used in genetics to describe the inheritance of certain characteristics or traits. Dominant traits are those that are expressed or seen when an individual carries one or two copies of the dominant allele. Recessive traits, on the other hand, are only expressed when an individual carries two copies of the recessive allele.

2. How are dominant and recessive traits inherited?

Ans. Dominant and recessive traits are inherited through the passing of genes from parents to their offspring. Each parent contributes one copy of each gene to their offspring. If a dominant allele is present, it will be expressed in the offspring regardless of the other allele. In the case of recessive traits, both copies of the gene must be recessive for the trait to be expressed in the offspring.

3. Can dominant traits skip generations?

Ans. Yes, dominant traits can skip generations. This can happen if an individual carrying the dominant allele does not pass it on to their offspring, or if the dominant allele is not expressed due to the presence of another dominant allele. Additionally, if an individual carrying the dominant trait does not have children, the trait may not be observed in subsequent generations.

4. Are all traits either dominant or recessive?

Ans. No, not all traits are either dominant or recessive. Some traits exhibit incomplete dominance, where neither allele is completely dominant over the other. In these cases, the phenotype of the offspring is a blend of the phenotypes of the parents. Additionally, there are traits that are influenced by multiple genes and environmental factors, making their inheritance more complex.

5. Can dominant traits be more common in a population?

Ans. Yes, dominant traits can be more common in a population. This is because dominant traits are expressed even if an individual carries only one copy of the dominant allele. Recessive traits, on the other hand, require both copies of the gene to be recessive for the trait to be expressed. As a result, dominant traits may appear more frequently in a population compared to recessive traits.
