MCQ IN MEDICINE

Detailed explanation-1: -Hosts raise offspring The parasites lay their own eggs into these nests so their nestlings share the food provided by the host. It may occur in other situations.

Detailed explanation-2: -The larvae find and recognise their hosts, in some cases even with species specificity, via complex sequences of behavioural patterns with which they successively respond to various environmental and host cues. There is often a surprisingly high diversity of host-recognition strategies.

Detailed explanation-3: -Brood Parasitism as a Reproductive Strategy Avian brood parasitism, or the laying of one’s eggs in the nest of another individual, is a reproductive strategy whereby parasites foist the cost of rearing their offspring onto another individual, the host (Davies 2000).

Detailed explanation-4: -Facultative brood parasites routinely make their own nests but they will sometimes deposit eggs in other birds’ nests. Obligate brood parasites, on the other hand, never make their own nests and they have no choice but to have someone else raise their babies.
