In K-selected species, the reproductive strategy is characterized by:
Answer: Few offspring with extensive parental care
K-selected species like elephants and humans produce few offspring but invest heavily in parental care, maximizing each individual offspring's probability of survival.
Hermaphroditism is most advantageous in which type of environment?
Answer: Sparse populations where finding a mate is difficult
Hermaphroditism increases reproductive success when finding mates is difficult because any individual encountered can serve as a potential reproductive partner.
According to Bateman's principle, the sex with greater parental investment will be:
Answer: More selective when choosing a mate
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.
Polyandry refers to a mating system in which:
Answer: One female mates with multiple males
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.
Oviparity as a reproductive strategy is defined as:
Answer: Laying eggs that develop and hatch externally
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.
Parthenogenesis is defined as which type of reproduction?
Answer: Development of an unfertilized egg into a new organism
Parthenogenesis is a form of asexual reproduction in which an unfertilized egg develops into a new individual, occurring naturally in some reptiles, insects, and fish.
