The "Chestnut vs. Black" DebateShortly after the rediscovery of Mendel's pea plant experiments, biologists began investigating whether Mendel's laws applied to other species, as well. In England, a debate broke out about whether the color of racehorses might be governed by Mendel's laws. Using the British Jockey Club registry of racehorse pedigrees, biologists made the following observations:1. A chestnut (red) stallion, when bred to chestnut mares, always produced chestnut foals. 2. Certain black stallions, when bred to chestnut mares, produced only black foals. 3. Other black stallions, when bred to chestnut mares, produced a mix of black foals and chestnut foals. 1. Which of the above observations is the most informative and why the information is valuable in regard to a Mendelian interpretation?

3. Other black stallions, when bred to chestnut mares, produced a mix of black foals and chestnut foals.

Explanation:

Mendelian is a botanist which contribute a lot in the field of genetics. His interpretation able the biologist for producing new species or hybrid organisms. From these observation taken by the biologist in the mating of different colors of male with the female horse, we concluded that the gene of the male horse remain dominant in the offspring while the genes of female horse is recessive in the F1 generation. But sometime, the crossing of different color horses also produced different offspring which resemblance to both father and mother horse.
