Question

Sunandini is
 A) A famous dancer from Kerala
B) Name of a marine fish found at coasts of Tamil Nadu
C) A cow formed by hybridization of Indian breed and Jersey cow
D) None of the above

Answer 1

Hint: Crossbreeding is only possible between animals from the same family or subfamily. Just one form of crossed breed, the geep (a goat-sheep mix), belongs to completely separate groups. These species are referred to as genetic chimaeras rather than genetic hybrids.


Complete answer:
They are well-known for their docile demeanour. Brown Swiss, the oldest of all dairy breeds, are thought to have originated around 4000 B.C. in Switzerland's valleys and mountain slopes, according to some historians. Brown Swiss are known for being docile and sweet. During one lactation, the average Brown Swiss cow can produce over 22,000 pounds of milk, or around 2,600 gallons of milk.
Brown Jersey cows are a small breed of dairy cattle known for their high butterfat content in milk, as well as their heat resistance, superior grazing capacity, and docile disposition, all of which make them ideal for island life. Jersey cows can produce up to 6 gallons of 5% butterfat milk each day. The Jersey breed is the world's second-largest dairy cattle breed.
The Holstein breed is known for producing a lot of milk, but it has less butterfat and protein in the milk than other breeds. Holstein cows are thought to have originated in the Netherlands about 2,000 years ago. The reasons for their popularity are obvious: superior quality, higher income over feed costs, superior genetic merit, and adaptability to a variety of environmental conditions.
Sunandini cattle were established in India by crossing unremarkable cattle with Brown Swiss (Indian breed), Jersey cattle, and Holstein Friesian cattle. We know that Sunandini is a cow formed by hybridization of Indian breed and Jersey cow. Therefore the correct answer is (C).

Therefore, the correct answer is option (C).
Note: A hybrid breed is one that is made up of at least two component breeds and is kept purebred to preserve heterosis in future generations without crossbreeding.
