Crossbreeding and Hints

Doing a Crossbreed and Suggestions

Cross Breeding for Tale 4 can be used on flax, flowers (Sea Lilies, Roses) vines, and wheat in a greenhouse. The tech is received from a University of Thought. Look under Techs Cross Breeding to see which regions have opened Cross Breeding.

Click on the greenhouse to find the "Crossbreeding..." option.

Note: With Tale 4 labeling of greenhouses was added under Utilities. It is 'highly' recommended to use this with some notation such as "#34 Fracture Energy" and record the cross on another page for later reference.

You may place two differently named plants (see note later to get around this exclusion) of the same type and species, one in the left cross and one in the right cross. For example, a sea lily cannot be crossed with an orchid, and neither can two different seasonal wheat types be crossed. If there is a plant in the left or right cross already, you will get the message "The left/right splint is already satured with whatever. Scrape away these seed and replace with whatever?". This can be handy if you have forgotten which plants are in the left and right crosses, say after you have been using solvents. If you would like to breed the same named plants you may go to any University of Worship (after gaining the Seed Registry tech at a University of Leadership) and rename a plant variety.

Make sure you have Nut's Essence in your Items, refresh the cross breeding window and click on "Initiate the Cross". A message in Main will tell you that it will take 15 minutes for the cross to finish. After 15 minutes another message will tell you that the cross is finished and which #number it is. The plants used in the splints will be consumed.

One child bulb or seed will be formed by taking a certain number of genes from the left side of the genome of the Left Cross and grafting it on to a certain number of genes taken from the right side of the genome of the Right Cross.

Example with Sea Lilies:
Fracture Left Cross ROYGROYGYORGORGOOO
Vampire Right Cross IYIYIOIYIOIO
Child Bulb (might grab from Fracture) ROYGROYG + OIYIOIO (from Vampire)

So if you understand what those genes and gene sets do in a genome you can make more intelligent crossbreeds for what your target is.

Length, Elongation and Shortening of the Genome

Sometimes a gene is added or eliminated at the splice point. If a gene is added, it will always be a doubled gene just left or right of the splice point. Statistics (90 experiments) show an approximate chance of 25% to get an elongation and 25% to get a shortening.

The genome length of the crossbred plant is by default the average length rounded up of the parents' genome. The rounding up on odd genome length sums is based on 20 tests that gave 10 results with rounded up average length, along with 3 results with 1 more gene (doubled gene at splice point) and 7 results with 1 less gene (eliminated gene at splice point).

To test the weight of a strain with molecular balance, set two objects on splints in a Greenhouse, and measure the weight with a King's Coin and Revelation Solvent - Crystal

[EDIT --Aperio 13:32, 10 June 2011 (EST)] This is a fine work and I don't have empirical experience to match Ariella's but I've always found these elongation/shortening claims suspicious (more like explaining planetary orbits with retrograde motion than shifting the center of the universe and applying ellipses). As a lifelong computer programmer, it is my belief that the statistical analysis supports randomized rounding more than a straightforward chance of elongation or shortening. To wit, if each splint is weighted average you are nearly always dealing with fractions for each. The game has to choose an integer value so it must round. If they both round down, you lose a gene. If they both round up, you gain a gene. If they split, the genome stays the same. In practice, it probably does match 25% / 50% / 25% (the mathematical proof is pretty trivial) but the mechanic would be fundamentally different and offers another view of how the 'doubled gene' might be derived. I propose to test crossing the same even-length genome (odd lengths might introduce rounding depending upon the order of cross-breeding operations) plant with itself to eliminate any rounding and to see if there is any change in its length or properties.

[EDIT User:Aperio Aperio 07:16, 19 July 2011 (EST) I'm examining this in more detail with the intent of establishing the crossing rules for T6. In a small sample size (10 crosses) of the Vine Appreciation against a renamed version of itself to eliminate rounding as a factor (a weighted average should be a true average and with a length of 12, there should be no rounding), I found 5 of 10 changed the Initial Grapes trait from 12 to 8(x1), 9(x2), and 10 (x2) suggesting some variation in the genetics. The other 5 could also be degenerate without immediately visible traits. In reviewing the obvious deviations, the 8 Initial Grapes vine actually lost a gene on the LEFT side of the left splint; an endpoint rather than the splice point. 2 of the other 4 vines are also demonstrating un-reconciled patterns and I need to invest more to better understand these variations.

Fun Sea Lily Breeding Hints

See Genomes page.

• Giant and Giantx2: Fracture on Left Cross, any other flower on Right Cross. Approximately 1 in 6 chance. ROYG is the giant gene set. There are two sets of those on the left side of the Fracture genome (ROYGROYG)YORGORGOOO.

• Dwarf and Semidwarf: Any flower on Left Cross, Fracture on Right Cross. Approximately 1 in 6 chance. GYOR is the dwarf gene set. One ROYG giant set plus one GYOR dwarf set will make a semidwarf lily size. Fracture has ROYGYOR in its genome which is actually a ROYG giant set with a GYOR dwarf set merged into it. But because there is also another ROYG on the left side we need the child genome to leave out that far left ROYG giant set or cut off part.

• Low fertilizer lily: Energy Left Cross, Crown Right Cross or vice versa. The 'V' gene lessens fertilizations by two standard ferts each. Energy conveniently has 5 'V' genes on each end of its genome. So for a really low fert lily, try some of each of the above, check the ferting rate and then cross a first generation Energy/Crown on the Left Cross and a Crown/Energy on the Right Cross for a second generation child bulb.
