Sexual Motivation

Sexual motivation refers to a person's overall desire for sexual activity. It is an unusual motivation. Generally, among lower animals, the term 'drive' is commonly referred to as sexual motivation. It means a certain internal force drags the animal to be involved in reproductive behavior. On the contrary, humans are not simply driven by any internal force; rather, the sexual motivation in humans is due to several factors such as biological (hormones, genes), environmental (familial upbringing, chemical exposure) and physiological factors (culture, desire) which further determine engagement in sexual activities.

How Can We Measure Allele Frequencies in Populations? In a population where the females have the allelic frequencies A = 0.35 and a = 0.65 and the frequencies for males are A = 0.1 and a = 0.9, how many generations will it take to reach HardyWeinberg equilibrium for both the allelic and the genotypic frequencies? Assume random mating and show the allelic and genotypic frequencies for each generation.

Perfect pitch is the ability to identify a note when it is sounded. In a study of this behavior, perfect pitch was found to predominate in females (24 out of 35 in one group). In one group of seven families, individuals in each family had perfect pitch. In two of those families, the affected individuals included a parent and a child. In another group of three families, three or more members (up to five) of each had perfect pitch, and in all three families, two generations were involved. Given this information, what, if any, conclusions can you draw about whether this behavioral trait might be genetic? How would you test your conclusion? What further evidence would be needed to confirm your conclusion?
INTERPRET DATA Look at the two graphs in Figure 52-21. In which experiment did the parentals in the experimental group guard the eggs more closely? In which experiment did the experimental parentals guard the young more closely? Account for these differences. RESULTS: Experiment 1: As indicated on the y-axis, which measures level of parental care, parentals reduced their level of guarding the eggs. Eight of the males in the experimental group abandoned their nests, and egg defense was significantly lower in this group compared with that in the control group. However, after eggs hatched, there was little difference in parental care of the young between the two groups. Experiment 2: During the egg phase, there was little difference in level of parental care between experimental and control groups. However, after eggs hatched, the experimental parentals significantly decreased their level of guarding the nest. CONCLUSION: Male bluegill sunfish adjust their level of parental care according to their level of perceived paternity. In Experiment 1, parentals provided less care when they perceived that the eggs may have been fertilized by sneaker males. After the eggs hatched, olfactory cues indicated that the offspring were indeed their own, and their level of care increased. In Experiment 2, parentals cared for the eggs even though some had been swapped. However, after they hatched, olfactory cues from the offspring indicated that they were not the parentals own offspring. The level of parental care decreased significantly. SOURCE: B.D.

Figure 1.15 Example of error bars in a graph. This graph was adapted from the peacock butterfly research described in Section 1.5. The researchers recorded the number of times each butterfly flicked its wings in response to an attack by a bird. The squares represent average frequency of wing flicking for each sample set of butterflies. The error bars that extend above and below the dots indicate the range of valuesthe sampling error. Figure It Out: What was the fastest rate at which a butterfly with no spots or sound flicked its wings?
