In the dragon goby, the aggressive and brightly ornamented males court the females, build elaborate nests and drive off predators to protect the young. What would you predict about reproductive success in the species?
Question 5 options:
M > F. Males are likely to have more offspring, on average than females do because of their hard work parenting and displaying.
M > F variance. Some males attract many females to their nests, whilst others are completely unsuccessful. Females will vary much less in reproductive success.
F > M variance. Compared to females, variance in reproductive success will likely be low in males.
M = F. Most males attract a single female to their nest, so reproductive success will not be very variable for either sex.
F > M. Females are likely to have more offspring, on average than males do because males do the hard work of parenting and displaying.
