Basic Trope: Offspring produced by Interspecies Romance between species X and Y are always of species X
- Straight: Xander, a human man, falls in love with Jade, an elf. They get married and have a child, and that child is 100% elven. They name her Jordan.
- Exaggerated:
- Xander is a black man so dark he could hide from a serial killer in a bucket of coal. Jade is so light skinned people have gone blind looking directly at her. Not to mention the fact Jade's physical build is completely different from any other human's. Jordan's expressed and recessive genetic make up has absolutely no connection to Xander despite him being her father, and is somehow more elven than her own mom despite being a halfling. Everyone thinks Jade is cheating on him.
- Humans come in contact with numerous elves, vampires, martians, and monster girls that effectively bred them extinction.
- Downplayed: Jordan comes out and is determined to be 70% elven and 30% human.
- Justified: Expressed elf traits are generally dominant over human traits, even if they are supposed to be a hybrid
- Inverted: ???
- Subverted: Jordan is initially born looking elven, but during her pre-teen years she begins to express human traits from her father.
- Despite external expressions Xavier was about 35% elf and Jordan's full elven appearance is a fluke.
- Double Subverted: ... but it was just a phase. She looks 100% elf again in adulthood.
- Parodied: Being an elf follows a one drop rule resulting in many "elves" with green skin and tusks, scaley hides and the ability to breath fire, a mass of tentacles which should be spatially impossible and a wolf.
- Zig Zagged: Jordan comes out a full elf, but the elf gene is literally "Dominant" in the sense of her alleles being Hh (H being elf, h being human). She marries another elf with Hh genes, have 4 kids and one of them have hh genetics, making the kid 100% human.
- Averted: Xander and Jade have a child who is 50% elven and 50% human
- Enforced: The artists had no idea how to design a human/elf hybrid, so just chose the more appealing design.
- Lampshaded: "You're sure she isn't cheating on you Xander?"
- Invoked: The writers considered the possible genetic hiccups of Interspecies Romance, and considered the possibility of overly dominant genes on one's part.
- Exploited: Since the child looks like an elf, Xander and Jade set up Jordan as an elf in preschool and beyond and claim she's adopted to avoid Half-Breed Discrimination.
- Defied: The scientists at the sperm bank make sure to select the sperm and egg combination that will result in 50/50% human/elf offspring.
- Discussed: ???
- Conversed: ???
- Deconstructed: Xander has trouble connecting with his own daughter since she looks nothing like him He believes she was cheating on him and had a child with another elf, but Jade knows she did not and is just as confused as him. This ends in a confrontation which leads to a divorce, and Jordan is ultimately orphaned.
- Reconstructed: A year or two later, Xander and Jade make up and decide to raise Jordan as well. He decides to accept Jordan as his biological daughter, and even if Jade cheated on him, the elf who impregnated her is too much of a loser to raise his own child and Xander ought' do it since he loves Jade anyway.
Dominant Species Genes had a child with another trope, but it just became another Dominant Species Genes
