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

검증된 단계별 안내

Understand the definitions of the terms provided in the options: a. Polygyny refers to a mating system where one male mates with multiple females. b. Polyandry refers to a mating system where one female mates with multiple males. c. Promiscuity involves both males and females having multiple mating partners without forming a stable pair bond. d. Certainty of paternity refers to the assurance a male has that he is the genetic father of the offspring.

Analyze the behavior described in the problem: The female spotted sandpiper mates with multiple males and leaves each male to incubate the eggs, repeating this process with different males.

Compare the behavior to the definitions: The behavior of the female mating with multiple males aligns with the definition of polyandry, where one female mates with several males.

Consider the role of the male in this behavior: The males are left to incubate the eggs, which is consistent with the female's strategy of mating with multiple partners and not forming a stable pair bond with any single male.

Conclude which term best describes the behavior: Based on the analysis, the term that best describes the behavior of the female spotted sandpiper is 'polyandry'.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Polyandry

Polyandry is a mating system where a female mates with multiple males. In the context of the spotted sandpipers, the female courts several males and leaves them to incubate her eggs, which is a classic example of polyandry. This strategy can increase genetic diversity and the chances of offspring survival.

Mating Systems

Mating systems refer to the patterns of mating behavior and reproductive strategies in animals. They include monogamy, polygyny, polyandry, and promiscuity. Understanding these systems helps explain the reproductive roles and strategies of different species, such as the female spotted sandpiper's behavior of mating with multiple males.

Certainty of Paternity

Certainty of paternity is the assurance a male has that he is the genetic father of the offspring he is caring for. In species with polyandrous systems, like the spotted sandpiper, males may have lower certainty of paternity, as females mate with multiple males, potentially leading to mixed paternity within a clutch.
