Step-by-step explanation:
When providing genetic counseling to an individual with a relative who has a complex trait, several types of information are used. These include empirical risk estimates based on averages from similar families, the mode of inheritance, Hardy-Weinberg law, and estimates of heritability from family studies. All of these types of information can provide insights into the likelihood of inheriting a complex trait and help guide genetic counseling.
