Knowledge/Comprehension Female spotted sandpipers aggressively court males and, after mating, leave the clutch of young for the male to incubate. This sequence may be repeated several times with different males until no available males remain, forcing the female to incubate her last clutch. Which of the following terms best describes this behavior? (A) polygyny (B) polyandry (C) promiscuity (D) certainty of paternity

Key Concepts

Polyandry

Polyandry is a mating system in which one female mates with multiple males during a breeding season, often transferring the majority of parental care responsibilities to the males. This strategy can arise when male parental investment is essential for the survival of the offspring, allowing the female to maximize her reproductive output by mating with several males.

Mating Systems

Mating systems refer to the organizational patterns in which animals reproduce, including how individuals select and mate with partners. These systems encompass various strategies such as monogamy, polygyny, promiscuity, and polyandry, each reflecting different patterns of mate selection, parental care, and reproductive investment among the sexes.
