Mule is obtained by crossing
A)Female donkey and male horse
B)Male donkey and female horse
C)Female horse and Male horse
D)Male donkey and Female donkey

Answer 1

Hint: For mules and hinnies, there are 63 chromosomes, a mixture of 64 horses and 62 donkeys. The distinct structure and number usually prohibits the chromosomes from properly pairing and producing productive embryos, leaving most mules infertile.

Complete answer:
A mule is the descendant of a male donkey (jack) and a female horse (mare). Horses and donkeys are separate species, with distinct chromosome numbers. A mule is better to procure than a hinny, which is the offspring of a female donkey (jenny) and a male horse, from the two first-generation hybrids of these two species (stallion).

The mule is respected because it is stronger than a horse of similar size and inherits the donkey sire's toughness and temperament, while it has its dam's size and ground-covering capacity, choosing to consume less food than a horse of similar size. Mules also tend to be more autonomous than other domesticated equines, rather than their parental breed, the donkey. A breed's superior male is a partner with another breed's superior female, called cross-breeding. The crossing between a male donkey with a female horse produces a mule.

Note: A hinny is a household equine hybrid that is the offspring of a male horse and a female butt (a jenny). It is the mutual cross of a male donkey (a jack) and a female horse that is the result of the more famous mule (a mare).
