Document Summary

Workers are adult non- reproductive females who clean, maintain, and repair the nest, gather food and water, and care for the young. Have a closer genome to sisters than offspring. What do the female reproductives release to attract males? pheromones. If not, which sex gets to found a new colony? male dies, female goes out to find a new colony. Who is the mother of the entire termite society? queen. Is this different than the ant colony, if so, how? yes, and yes ant does not have a king. Queen releases chemicals that make the colony sterile. Produce toxins to ward off enemies (1st caste) . Soldiers are non-fertile adult male and females, and have large mandibles and protect the colony from intruders. Bring up material to patch up hole . Workers clean, maintain, and repair the nest, gather food and water, care for the young, and construct new tunnels and galleries as the colony grows.

Explain the unusual sex-determining system of eusocial insects like ants and bees. Why does this system favor the evolution of a non-reproductive worker caste? Why are workers all female? Why do workers sacrifice their own reproductive success to help the queen?

Explain why a queen bee produces equal numbers of sons and daughters, but workers favor a 3:1 ratio of daughters to sons among the queen’s offspring.

Under what conditions can behavior for reciprocal altruism (individuals helping each other) evolve between non-relatives? What does such a system depend upon?

Which of the following statements regarding the urogential tracts of humans is incorrect?

A. The male urinary tract and male reproductive tract have the same type of normal flora

B. The female urinary tract and female reproductive tract have the same type of normal flora

C. The male reproductive tract is largely sterile except for the portion nearest the external opening, whereas the female reproductive tract is generally well-colonized with normal flora.

D. Both the male urinary tract and the female urinary tract are largely sterile except for the portion of the urethra nearest the urethral opening

1.Why would you predict that females in species with internal fertilization and long periods of gestation would be choosier in selecting their mates than females in other species that lack these traits?

2.As we talked about in elephant seals, in many species, there is much greater variance in male reproductive success than in female reproductive success. This could result from a few dominant males controlling the access to the breeding grounds the females need to give birth. There are other ways, however, to get the same pattern of variance in male reproductive success WITHOUT males controlling access to a resource or to females. How might you get the same variance in male reproductive success via intersexual selection?
