Mockingbirds typically lay 3 eggs. If the mockingbird produces more than three eggs their young are often malnourished because they have so many to feed. If less than 3 eggs are produced they may not have any viable offspring. This is an example of

- Many factors influence a species mode of reproduction. Use the descriptions of the following species to predict what system of hermaphroditism they probably display. 1. Individuals rarely disperse once they are sexually mature, and the largest males get the most matings. Females protect the eggs. [Select] 2. Resources are of uniform quality and evenly dispersed, so males are unable to monopolize them. Females are larger than males; Males protect the eggs. [Select] 3. Individuals are solitary, rarely meet others, and have no way of knowing the sex ratio in the population. There is no parental care.

In some species, the neotenic characteristics have become a permanent state of the species (obligate neoteny = paedogenesis; both are called paedomorphic conditions). These have lost the ability to undergo complete metamorphosis (hellbender, amphiuma, and mudpuppy). In others, the animal does not undergo complete metamorphosis in nature, but can be induced to do so in the lab. An example of this is the Mexican axolotl (Ambystoma mexicanum), a large gilled salamander found in Mexico. In some species of salamanders, members of a population exhibit neoteny only when they are under stressful environmental conditions (such as crowding, scarce food, low concentrations of trace elements). This is called facultative neoteny. Tiger Salamanders (Ambvstoma tigrinum) frequently do this, but local populations of marbled salamanders show a…arrow_forwardPlease help asaparrow_forward
