If both genes are recessive, the trait controlled by these genes will typically be expressed. For instance, if both parents carry a recessive gene for blue eyes, a child may exhibit blue eyes. Recessive traits only manifest when no dominant gene is present to mask them.

FAQs & Answers

  1. What is the difference between recessive and dominant genes? Recessive genes require two copies for a trait to be expressed, while dominant genes only need one. Dominant traits mask the effects of recessive traits.
  2. Can recessive traits skip generations? Yes, recessive traits can skip generations if they are carried by parents without being expressed in them.
  3. How do I know if I carry a recessive gene? Genetic testing can determine if you carry recessive genes, especially if there is a family history of certain traits or conditions.
