Lisa was working on her day's work. This scientific endeavor was her looking at genetics she was collecting all the genetic information about her family as a case study to see how genes work between family members. This had been an arduous affair because she had to collect DNA from her family members and they weren't always willing to have this happen. There were great things that could be done with this information: solve any future disease chances, why Lincoln's hair is white, and so much more. Lisa had collected information on all the members of her household, including herself and had was now looking at the results.

She decided to look at her genetic composition first.

"I do wonder why out of 13 people in this house, am I the one who has to wear glasses," she said out loud.

The first thing was do a match up of her and her parents' genes. This would give her a clear understanding of what genes she inherited from her mother and father. She already had some theories about what, but now she could confirm if she was right.

"I'm sure inherited my brown hair from the paternal unit, it's the dominant gene unlike the blonde girls who got Mom's blonde recessive gene, I am sure Lincoln got his white hair from mother as well.", she explained.

Time marched on as she looked through all the information there was a lot of detail that couldn't be skipped since it was so intricate. There was something of note that came through that jarred her something wasn't adding up at all.

"This is not adding up, parents provide about 50% each of their genetic code to their off spring," she replied. "but my DNA isn't matching 50/50, it's 25% from each, maybe there's something corrupted with the sample."

She examined Lori's DNA and did the same test she did before looking at the matches comparted to her parental units. After some time, her tests concluded that Lori had the standard 50/50 match up.

"Well my parental units' DNA doesn't seem to be corrupted."

Then she took her sample and matched it with Lori's since it would be quicker to compare than trying to look at another sibling. She had a 50% match with Lori, which made some sense, because siblings would have that match up. Then she took Leni's DNA data and tested it against her own and noticed that she only shared 25% with Leni. This didn't make sense how can someone share 50% of DNA with one sister but only 25% with another? She decided to skip to Lincoln and see if his DNA matched their parents.

"Welp, my only brother's DNA matches with our parents, in fact it matches more than my own, he's not adopted, but I don't know what is going with mine."

A scientist works hard for their answers and she pressed on, not noticing that Lilly was back in their shared room taking her afternoon nap. All her siblings' DNA, except Lori's, came up as 25% match to hers. There was a set of DNAs in her code that had no match to her parents, or siblings. There was another person in her DNA, someone whom she didn't know who it was, or why there was. Her initial theory was that her parents really wanted a 10th child but were having some trouble so they had a surrogate. This was a little off to her since that past siblings and Lilly all didn't seem to have this problem. Was she a test for a three-parent birth?

"My other theory is way to silly to think about at all, I can't even verbalize it."

She was hungry and hadn't eaten most of the day, so she left her room and went to the kitchen to see what she could find. She saw Lori talking on her cell phone to Bobby like always, even when he moved, they still talked a lot on the phone. Leni was helping Lola with her next pageant outfit. Lincoln was laying on the couch reading a comic book in only his underwear, and Lana was teaching her snake some tricks. Lisa's mind was wrapped around the data she had collected and the results she found where she accidently bumped into Lucy.

"Me apologizes, older sister," she said.

"No problems, Lisa," Lucy said in her normal monotone voice.

"Older, sister," Lisa Thought, "I might not be."

Lisa went back in her room where Lilly was awake and wanting out of her crib. Since Lisa was kind of short, had to get a stool to get Lilly out.

She rolled out her chalkboard, while Lilly played with some baby toys and she made a drawing of two boxes with a line linking them. Then she drew a line under that one and branched it out with more lines making a "tree" Then she wrote in the names of her parents, her siblings, and herself.

"Alright, my DNA result shows that mother and father have only 25% of the DNA sharing with me, and everyone but Lori is the same result, I share 50% with Lori." She said.

"Yori," Lilly said trying to say Lori.

"Everything comes up to Lori, being a key figure to my answer in this mystery a link, if you will."

"Lincoln," said Lilly.

"You are good at saying his name, Lilly, don't worry you'll soon have a great vocabulary and be expressing words like the rest of us."

"The hard part is I am going to have to talk to Lori and do an inquiry."
