Despite this diversity, the mixed-race people on the show are never talked about; "mixed-race people" meaning individuals who are mixed race, not a group that's mixed.
I was going to call this "mixed-race people on Lost", then I noticed everyone here is female. I changed it to "women" to be more specific.
Andrea Gabriel
Her character, Nadia Jaseem, is Arab Iraqi but she is mixed Italian, Iranian, Romanian, and Russian. BTW, Iranians aren't Arabs because they don't speak Arabic, however they're Middle Eastern, and Arabs are too.

Reiko Aylesworth
Her first name is a hint of her quarter-Japanese heritage, which also includes Welsh and Dutch. She's in three episodes in season 5.

Tamara Taylor
She was born and raised in Canada and is mixed Black and White. She plays Walt Lloyd's mom and Michael's ex, and appears in two episodes, one in season 1 and one in season 2.

Rachel Ticotin
She portrays the police captain and mother of Ana Lucia Cortez, who's played by Michelle Rodriguez, who is also on this list. Ticotin is mixed Puerto Rican and Russian Jewish.

Kimberly Estrada
The only episode she's in is "Not in Portland" in season 3, where she plays the girlfriend of one of the main character's ex-husband. She is mixed Chinese and Spanish.

Zuleikha Robinson
Her role is Ilana Verdansky, who first appears in season 5 and becomes part of the main cast in season 6. Robinson was born in England, grew up in Thailand and Malaysia, and is mixed English, Burmese, Indian, Iranian, and Scottish.

Marsha Thomason
Like her character, Naomi Dorrit, she's from Manchester, England. She is mixed English and Jamaican (White and Black, respectively).

Kiele Sanchez
Her role is Nikki Fernandez, one of the main characters in season 3. Her heritage is mixed French and Puerto Rican.

Yvonne Midkiff
She plays a receptionist in a lawyer's office in the season 6 episode "The Last Recruit". She was born in the Philippines, grew up in Oklahoma, and now lives in Hawaii.
Hawaii is where the show was made and is also the US state with the highest percentage of mixed-race people.

Maybe Hawaii's multiracial vibe rubbed off on the producers when they casted the actresses (they chose an unusually high number of multiethnic ladies...).
---
The following actresses are mixed in a different way; they each have multiple ethnicities in one racial group. This is sometimes called intra-ethnic or intra-racial.
Like somebody who's mixed Indonesian and Filipino (Asian), or someone who's mixed Puerto Rican and Mexican (Latino), or a Polish / German / Italian / Russian / Swedish person (White).
Something worth mentioning is all of the below play a mother or a daughter of another woman on this list. Maybe this means Hollywood is starting to portray mixed descent more accurately.
Michelle Rodriguez
Not only is she mixed Dominican and Puerto Rican but she grew up in both of the countries too. She was a regular cast member in season 2 and made cameos in seasons 5 and 6.

Melissa Farman
Her mother is White American and her dad is French (White from France), and she was raised bilingual in English and French, both of which she speaks on the show.
She plays a younger Danielle Rousseau, whose daughter is Alex Rousseau, who is portrayed by the next girl on this list.

Tania Raymonde
Like her character Alex Rousseau, she's of French descent, but she's also Russian and she might be Jewish too, since her real last name is Katz.

How come there's many mixed girls but not mixed guys?
