Game Development

Horns

The basic horn genetic model from Showcattle is included as well as scurs.

Added the African horn gene as well.

Horn genetics will be based entirely on this NCSU article.

Colors

Using this article as the basis for color genetics again.

Extension Gene Explanation...

https://vgl.ucdavis.edu/test/mc1r-cattle

• Cattle with ED/ED genotype will have a jet black base color and cannot produce red offspring. They will transmit this dominant black variant to all of their offspring.
• Cattle with ED/E+ genotype will have a jet black base color and are carriers of the wild type variant. They will transmit this wild type variant to 50% of their offspring. Matings between two wild type carriers result in a 25% chance of producing a calf with wild type base coloration.
• Cattle with ED/e genotype will have a jet black base color and are carriers of the recessive red variant. They will transmit this recessive red variant to 50% of their offspring. Matings between two recessive red carriers result in a 25% chance of producing a calf with recessive red base coloration.
• Cattle with E+/E+ genotype will have wild type base coloration (reddish brown to brownish black base coloration). They will transmit this wild type variant to all of their offspring.
• Cattle with E+/e genotype will have wild type base coloration (reddish brown to brownish black base coloration) and are carriers of the recessive red variant. They will transmit this recessive red variant to 50% of their offspring. Matings between two recessive red carriers result in a 25% chance of producing a calf with recessive red base coloration.
• Cattle with e/e genotype will have red base coloration. They will transmit this recessive red variant to all of their offspring. All calves produced from matings with other e/e genotype cattle will have recessive red base coloration.
