Question 1

In K-selected species, the reproductive strategy is characterized by:

Accepted Answer

Few offspring with extensive parental care

Answer

K-selected species like elephants and humans produce few offspring but invest heavily in parental care, maximizing each individual offspring's probability of survival.

Question 2

Hermaphroditism is most advantageous in which type of environment?

Accepted Answer

Sparse populations where finding a mate is difficult

Answer

Hermaphroditism increases reproductive success when finding mates is difficult because any individual encountered can serve as a potential reproductive partner.

Question 3

According to Bateman's principle, the sex with greater parental investment will be:

Accepted Answer

Bateman's principle states that the sex investing more in offspring (typically females) becomes choosier about mates, while the less-investing sex competes more actively for access.

Question 4

Polyandry refers to a mating system in which:

Accepted Answer

One female mates with multiple males

Answer

Polyandry is a mating system where one female mates with multiple males, seen in species like jacanas where males provide most of the parental care.

Question 5

Oviparity as a reproductive strategy is defined as:

Accepted Answer

Laying eggs that develop and hatch externally

Answer

Oviparous animals lay externally fertilized or fertilized eggs that develop outside the mother's body, as seen in birds, most reptiles, and the majority of fish species.
