The advantage of this is so that a number of offspring can be produced from a single organism swiftly. However the disadvantages of asexual reproduction are that due to the swiftness of asexual reproduction there is not enough time to develop variation between the offspring so a clone is created in which case if the parent has a weakness that weakness is then passed onto the offspring. The first advantage of sexual reproduction is that due to sexual reproduction requiring two partners the offspring has more chance of variation as it inherits different cells from each partner. The advantage of variety in this case ensures the death of a species with a certain weak element and offers the chance of adaptation so that when the animal reproduces, the offspring will inherit the adaptive traits. Therefore, the advantage of sexual reproduction is that it creates an individual with a greater chance of survival.
The relationship between sexual selection and reproductive behaviour Darwin states that animals possess features that make them attractive to the opposite sex and allow them to compete better against their own sex. Any trait that enhances reproductive success will be passed down and enhanced over evolutionary time. A human example suggested by Pagel et al is the relatively hairlessness of a human beings compared with other apes, this is due to the hairless feature allowed our ancestors to keep cool as well as appearing more hygienic. This then becomes more desirable in a mate and is the result of sexual selection. There are some cases though that seems to go against this, the peacock’s tail for example.
That means that although in evolutionary terms a male is able to reproduce at a far higher rate that females in humans they are more likely to settle on one sexual partner, in accordance with the fact that the males resources will be limited and stretched thin over a long period of time, it would not be possible to rear multiple offspring with different sexual partners. Studies have found that in humans males link young youthful good lucks with fertility; this is because a clear complexion, health teeth and a young athletic build equals good health in humans and means the person is less likely to catch disease and illnesses and more likely to be fertile and produce a healthier offspring (Buss, 1995). This is important in sexual selection because of the level of investment that a male
Females, on the other hand, follow their gut feelings and their “female intuition” and employ the “‘tend or befriend’” strategy. Both genders have some similarities but not so much so that we can pass off as the opposite gender. Our feeling and reactions are what makes us a male or female. Hormones such as testosterone have some affect but our emotions largely make us who we
When their cells go through aging and get damage, women have a choice in terms of genes, whether on one X chromosome or the other. If one X chromosome gets damage, women still have another X chromosome which will protect them from genes disease. On the other hand, this situation will be different for men because they just have one X chromosome in their body. As a result, if the X chromosome gets damaged by age, men will not be protected by the other chromosome because they have different type of chromosome. This biological aspect make women can live longer than men because they get better protection from their own body.
Like hunger and thirst, sex is also an appetite and it can be satisfied in a number of ways (even those seen as irregular). Whether they are natural or not is no longer an issue because once something is established as sexual, it is sexual. The basic structure of the argument is: appetites are all normal; sex is an appetite; therefore, all sex is normal. Nagel then argues back that even appetite can be perverse by giving examples of how one could be seen as gastronomically perverted; sexual desire has its own characteristics and more complicated which allows perversions to occur. Furthermore, an individual which one desires are called objects and they consist of properties that attract the person.
Yet we see media encouraging the notion that you must be beautiful not smart to find a significant other. Equally, we see media encouraging that to be attractive to females you must have be masculine, strong, and handsome. Feminism currently works to defeat these standards put upon males and females by society. A beautiful reference Quindlen made to the shifting feminist agenda is that of expectations. As females, we are now able to legally do everything a male can do, yet now we are expected to do it even better.
We are more likely to form a relationship with those people who are associated with pleasant event e.g. we are more likely to like someone when we are in a happy mood opposed to unhappy. Support for this theory comes from Griffitt and Guay, they found that higher ratings were given when the experimenter had positively evaluated the participants, thus showing the importance of positive stimuli in relationship formation. Although, the reward / need satisfaction theory doesn’t take into account cultural and gender differences in the formation of romantic relationships. Lott suggests that in many cultures are more focused on the needs of others rather than receiving reinforcement.
In the experimental condition, the participants were exposed to sexually-biased advertisements. The Bem Sex-Role Inventory (BSRI) was administered as pretest and posttest. It was hypothesized that participants in the experimental group would show a more feminine sex-role perception after the experiment. The results showed a shift towards a more feminine sex-role perception in both groups at posttest. next page To what extent do advertisements affect our sex-role perception?
Across the centuries women were repudiated entitlements equal to men and due the assembly of gender, men were given higher power above women. This has managed to disparate arguments of what is indeed the act of the woman in a gendered area and clashing for the credit of a female species (Rosenstand, 2009: 586). 3 DIFFERENCES BETWEEN SEX AND GENDER Liberal feminists squabble that both boys and girls across origin are born the alike merely the area will craft them on how ought to a man and a woman behave in a gender crafted society. Sex could be described as biological contrasts both inner and external organs. Gender could denote to communal institutionalization of sexual differences; they believed gender is utilized by those who comprehend not merely sexual inequality but far of sexual contrasts to be communal craft were by men and women are crafted to behave in precise methods that could be categorized as feminine of masculine (Okin, 1989: 116).
