What is alyssa and gisele thompson ethnicity?

As an AI language model, I am not able to retrieve specific personal information about individuals unless it was previously shared publicly. However, based on the name alone, it is not possible to determine Alyssa and Gisele Thompson's ethnicity. Ethnicity is a complex concept that involves various aspects like cultural traditions, language, ancestry, nationality, and more. It's worth noting that one's name is not a reliable way to identify their ethnicity. People may have names that are commonly associated with different ethnicities, but it's essential to consider that a person's background is influenced by several factors.
