Dominant traits are those that are more likely to be expressed in an individual. These include brown eyes, dark hair, and freckles. In genetic terms, if an individual inherits differing traits from each parent, the dominant trait will mask the recessive one. For example, having one allele for brown eyes and one for blue will typically result in brown eyes.

FAQs & Answers

  1. What are dominant traits? Dominant traits are characteristics that are more likely to be expressed in an individual when inherited.
  2. How are dominant traits inherited? Dominant traits are inherited when an individual receives at least one dominant allele from a parent.
  3. What is the difference between dominant and recessive traits? Dominant traits are expressed over recessive traits, which require two copies to be visible.
  4. Can two recessive parents have a dominant trait child? No, if both parents carry only recessive alleles, their offspring cannot express a dominant trait.
