Genetic disorders are inheritable to the next generations through gametes. Any abnormalities or changes in the genes of a genome can be replicated and transferred to offspring. Such genetic disorders are treated by gene therapy and prevented by genetic counseling.
Genetic counseling involves careful observation of family genetic (pedigree chart) patterns. Based on the pedigree chart analysis, the incidence of a genetic disorder and its risk of transmitting to the next generations can be avoided. Hence, option (a, b, e) is the correct answer.
Option (a) is given as "Having a brother who died of a myocardial infarction at age 29".
Option (b) is given as "Having a family member who has been diagnosed with more than one type of cancer".
Option (e) is given as "Having a maternal grandmother, two maternal aunts, and a sister who were diagnosed with colon cancer".
