Our Father - S3-E1
Continuity mistake: When Dexter gets out of the car and talks to his sister, the strap on the camera keeps flipping back and forth. (00:52:45)
Our Father - S3-E1
Continuity mistake: When Dexter and Vince are next to the dead girl, in the side shot, the tied string from her top is visible on her back and her hair is to the side. But in the overhead shot of her, her hair is covering the tied string and spread more over her back.
Our Father - S3-E1
Other mistake: When Debra is talking about her new haircut, she states that she has changed her hair "for the first time since she was 8." However in various flashbacks throughout the show she has drastically different hairstyles from her 'usual'.
The Lion Sleeps Tonight - S3-E3
Continuity mistake: A man in a blue t-shirt and holding two beer cups is seen walking in front across Dexter and Miguel. In the next shot the same man is seen walking behind them. (00:15:40)
The Lion Sleeps Tonight - S3-E3
Visible crew/equipment: While at the cemetery a reflector (to brighten the actors' faces) is regularly visible in the DA's glasses.
Continuity mistake: Deborah walks out with the yellow shirted man in front of her. Next shot after Quin leaves, the same man re-exits the room. (00:14:00)
Continuity mistake: When Dexter leaves on his boat there are fishing poles behind his seat, but when he turns back around and you see him going away on the boat they have gone.
Easy as Pie - S3-E7
Continuity mistake: When Dexter and Rita are having dinner at Miguel's house, his wife drops a glass. She sets 2 other glasses on the island in the kitchen. After a cut to another shot the 2 glasses are now on the counter by the sink, before she bends down and picks up the glass she dropped. (00:39:50)
Continuity mistake: In the scene where Dexter is playing a video game on Miguel's office computer, Miguel is shown to close the game down. But in the next shot the game is visible on the screen before disappearing again in the shot afterwards. Additionally, the video game shown is Halo 3, which is only available on Xbox 360. When Miguel 'closes' the game, he is actually alt-tabbing from a "TWVidpla" window to "Plaindesktop.bmp," and a laptop battery indicator is visible. (00:12:55)
Factual error: When Maria is looking at Miguel's file, we see his Florida Driver's License. The expires date is wrong. FL driver's licenses expire on the person's birthday, not on the day the license was issued.
Do You Take Dexter Morgan? - S3-E12
Other mistake: The marriage certificate for Rita's first marriage shows her date of birth as 04-19-1989 and Dexter states she married at 16. The marriage date is 08-16-1989, when she would have been 4 months old. She also would only be 17 at the start of the series (2006) if she was born in 1989. (00:13:45)
Do You Take Dexter Morgan? - S3-E12
Other mistake: Debra is checking her email for the traffic cam photo of George King. The sender is labeled "Miami Metro Robbery Div." and the subject is "Photo of George King." However, after opening the email, the send is then a malformed email address of Det.Robertson.Robbery|MiamiMetroPolice.web with a recipient address of Debra.Morgan.Homicide|MiamiMetroPolice.wed (wed, not web), with a subject of "B. O. L. O. Match - George King." (00:26:38)
Do You Take Dexter Morgan? - S3-E12
Character mistake: The petition for dissolution of marriage was filed on Jan 6, 1990 which is less than 5 months of marriage. However, the duration of the marriage says it's been 6 months.
Answer: The short answer is yes, it could. but, it would have to be set up to analyze results to differentiate species. The sequencer will report the base pairs for any properly prepared sample, but interpreting the results is a software package. The software is available, but I would think it unlikely that an analysis package used in a forensics lab would have the capability to be so specific. More likely it would report "Non Human Sequences Found."
