BIO 204 Lecture Quiz 9
1. You decide to study two species of birds, both of which form monogamous
pairs (one male and one female). In species 1, you find that the eggs in a
pair's nest are in fact almost always the offspring of that pair. In species 2, you
are surprised to find that many of the eggs in a nest were actually fathered
by males of neighboring pairs. Apparently, mating outside of monogamous
pairings is widespread in species 2. What would you expect to observe if you
examined the reproductive tracts of the female birds in the species?: Females of
species 2 would have sperm from multiple males in their reproductive tracts.
2. From earliest (first to occur) to latest (last to occur), the overall sequence of
early animal development proceeds in which of the following sequences?: cleav-
age ’gastrulation ’organogenesis
3. Sexual reproduction:: can produce diverse phenotypes that may enhance survival of a population in a
