Final answer:
Under the Texas Fair Housing Act, ancestry is a protected class not covered by the Federal Fair Housing Act, providing broader protections against housing discrimination in the state of Texas.
Step-by-step explanation:
The protected class under the Texas Fair Housing Act which is not protected under the Federal Fair Housing Act is ancestry. While the Federal Fair Housing Act of 1968, also known as the Civil Rights Act of 1968, bans discrimination in the sale, rental of housing, and mortgage lending based on race, color, national origin, religion, sex, familial status, and disability, it does not include ancestry as a specific category. However, the state of Texas provides broader protections to include ancestry within its fair housing laws.
This expansion shows the state's commitment to ensuring all individuals, regardless of their lineage or family history, are protected from housing discrimination within its jurisdiction. Under Texas law, discrimination based on financial status is prohibited when it comes to housing, but the Federal law does not specifically include financial status as a protected class.
