How might carriers of deleterious genes be recognized?
What will be an ideal response
Carriers of deleterious genes may be recognized if their offspring show symptoms of the condition or disease caused by the deleterious gene. Because the genes are usually recessive, they would show phenotypically only if the offspring received the recessive genes from both parents. A pedigree analysis may be done to trace a particular trait back through several generations. Blood chemistry tests (and DNA probing) may also be done if particular genetic traits are suspected.
