Identical monozygotic twins do indeed share the same DNA because they develop from the same parental egg-sperm combination. While their genetics are identical, physical and some behavioral differences are generally attributed to something called "epigenetics.
Researchers have been working on making sense of epigenetic mechanisms and their effects on the expression of phenotypic traits, with rapid advances in their understanding especially within the last 5—10 years.
Studying the physical differences between twins has been crucial in assessing how the environment impacts the expression of complex traits, and what kinds of factors may be involved. I also really enjoy the science related videos produced by Scishow. HERE is their discussion of epigenetics. One, of course, is so that they can be visually distinguishable onscreen. Insofar as they may make choices to act in the world according the principles and concerns that drive them, they also make choices about how they choose to present themselves stylistically like, for example, one may simply decide to artificially color her hair.
Cosima tells Sarah that she wanted to explain the whole clone thing more softly after Alison blurts it out. Cosima meets Felix Dawkins at Alison's house and tells Sarah to bring her Katja's briefcase if she wants more answers. Sarah calls Cosima for help when the police discover Katja's body and she finds out about Sarah's criminal record.
Sarah meets Cosima at a local bar on the day she is set to return to Minneapolis for her studies and gives her the briefcase. Cosima tells Sarah that she needs to keep being Beth to learn more about who's killing them.
Cosima tells her to hinder the police's investigation into Katja's identity. Sarah calls Cosima, now back at school, and tells her that Katja's killer contacted Beth's partner Arthur Bell.
Cosima arranges for Alison to teach Sarah how to shoot a gun. In " Effects of External Conditions ", Cosima examines Helena's knife and tries to explain her motives for killing in a video chat with Sarah and Felix. Cosima deduces that Beth shot her on purpose. Sarah tells Cosima that Helena was at the police station and wants to meet her. Cosima explains that Helena is on a religious crusade to kill the clones because Helena believes them to be abominations. In Conditions of Existence , Cosima explains, over video chat, to Sarah, Felix and Alison that the object in her mouth was an electrode from an EEG helmet which monitors electrical activity in the brain.
Cosima says that if it was her experiment she'd put an observer close to the subject. In the lab, Cosima is testing the clone samples. She asks Scott to help her but doesn't tell him what it's for. She notices an upset Delphine who leaves behind her report card. Cosima sneaks a peek at it and then follows Delphine, finding her crying. They introduce themselves properly and clearly hit it off.
Cosima tells her that she's studying evo-devo evolutionary development. Cosima calls Sarah after Felix plays her the recording of Paul and Olivier and tells her that it's a double blind so Paul may not even know he's watching a clone. Cosima tells Sarah she has a monitor dilemma too and Sarah tells her to stay away and "stick to the science". Cosima is annoyed, saying "What am I, the geek monkey, now? Aldous Leekie - and asks her to come with her.
After the talk, Dr. Leekie chats with Cosima and Delphine and tells them to have a look at Dyad. Cosima steals two bottles of wine and her and Delphine run across campus, holding hands. Cosima tells Delphine that she is going to get her so baked one day. Delphine kisses her on each cheek and leaves. Cosima says that this is different than Alison and Donnie as she's the one monitoring Delphine. Later, Sarah phones Cosima to tell her Helena's back. Cosima asks if Sarah knows Dr. Leekie, saying he's the poster boy for Neolution.
Sarah tells her that Olivier owns a club called Neolution. Cosima tells Sarah that she went with Delphine to one of Leekie's lectures causing them fight and hang up. Delphine arrives at Cosima's apartment and she's not ready telling her, "I'm kind of always late, though, so, kind of always sorry".
They go to dinner and Delphine tells her she should have left her boyfriend when she left Paris and that she was the one who stopped him joining her. Cosima says "You're the asshole? Leekie to join them, with Cosima unimpressed. Dr Leekie approaches Cosima and offers her a job at Dyad Institute along with her complete genome sequence. She arrives at Felix's place where she's coughing up blood. Delphine arrives shortly after and tells her that the genome Leekie gave is not complete, the marker is scrubbed out.
With the help of Delphine she manages to decode her marker. It is actually a patent with the sentence "This organism and derivative genetic material is restricted intellectual property" written in DNA. In the Season 3 premiere , Cosima is living in Felix's loft and appears to be healthier. She speaks to Kira about her dream from the Season 2 finale and her "coming back" to Kira. Their conversation is interrupted by Delphine, who tells Cosima that she is taking over some of Rachel's duties at Dyad, effectively putting her in charge.
She also breaks up with Cosima, and tells her that she is keeping her promise to love and care for each Leda clone equally. She tasks Cosima with finding a cure for herself and her sisters, before tearfully leaving the loft. Later that day, Scott comes to perform a checkup.

Nothing more unfortunately. Improve this answer. Andrew Martin Andrew Martin Aesthetically, I realized they were using the glasses to differentiate between characters a little more. I mean, they can only have so many hair styles and accents, right?
I hadn't heard of the "tired eyes" issue with Cosima, though, so kewl. And yet they all have the same crooked teeth! Featured on Meta.
