Nope, shouldn't mess up the genetics. Best way I can explain the genetics is that for tulips there are three 'genes' : Red, Yellow and White.
- Each of these genes have a value from 0 to 2. Orange tulips from seed red and seed yellow will have the following genes: 1, 1, 0.
- Pairing two of these together, you will have a 37.5% chance for an orange tulip to spawn.
- 25% of these orange tulips will have 1, 1, 0 while the other 12.5% of these orange tulips will have 1, 2, 0 which are the same genes as ones found on hybrid islands if the player is able to come across them.
- By replacing an orange tulip with 1, 1, 0 with a 1, 2, 0 orange tulip your odds of getting an orange tulip increase to 50%.
- 25% of those orange tulips will be 1, 1, 0 while the other 25% will be 1, 2, 0. Your odds of a purple tulip also increase to 12.5% while also decreasing the chance of a black tulip to 12.5%.
- Getting a second 1, 2, 0 and replacing the remaining 1, 1, 0 will make it so purple tulips are 25%.
Edit: And this is why I decided to keep this stuff off my main post, gets super confusing lol.
