Final answer:

Step-by-step explanation:
The statement that is supported by research on lesbian and gay families is:
- Children in lesbian and gay families do not differ from the children of heterosexual parents in mental health, quality of life, or sexual orientation.
Research has shown that there is no quantifiable data to support the notion that opposite-sex parenting is any better than same-sex parenting. In fact, children of lesbian couples have slightly lower rates of behavioral problems and higher rates of self-esteem compared to children of heterosexual parents. Further research indicates that the legalization of same-sex marriage has had positive outcomes for the emotional and mental well-being of LGBTQ+ individuals.
