Question

India's indigenous pigs generally give birth to young ones at a time?
A.6-8
B.4-6
C.2-4
D.8-10

Answer 1

Hint:The action of giving birth to young ones is called parturition. Mammals give birth to offspring. Term indigenous stands for native to particular regions. Pigs are omnivorous mammals.

Complete answer:
Litter is giving birth to multiple offspring once at a time. Litter term is generally used for mammals but can be used for any animal giving multiple births to young ones.
Animals from the same litter are called litter-mates. Litter protects our young ones from predators to some extent.
The probability of surviving all the organisms from the litter is very less. It is possible in the case of domesticated dogs and cats under human care.
India's indigenous pigs generally give birth to 4-6 young ones at a time.

So, the correct answer to the given question is option B.4-6.

Additional information:
The litter size of dogs is four to five puppies whereas, the litter size of cats is two to five kittens.
Litter competes for food and space among themselves since birth. Only the fittest among all the litter tends to survive i.e. survival probability for fit litter is more than others.

Note: In mammals the process of parturition is initiated by hormones which contract the uterine muscular wall.
Large mammals give rise to a single offspring at one birth. The gestation period of an organism is the period of development of the embryo. The gestation period of a human 480 is days.
