Sex selection

key role in many aspects of life, whether human or animal. This paper will discuss the many dietary and environmental factors that affect the sexual selection as well as sexual dimorphism, specifically in lizards. Sexual selection is a type of natural selection where one sex does the choosing of mates for the other sex, and members of the same sex are rooted against each other to compete for mates. In order for a mate to attract a female with a high reproductive fitness, it is important to do a

boy or a girl?” Parents have the opportunity to find out the sex of the baby beforehand by going through a procedure known as an ultrasound. An ultrasound relies on sound waves to create an image of the baby in the uterus. This safe and painless procedure normally takes place between 18-20 weeks of pregnancy. Thanks to the advancement in our technology, parents have the ability to determine the gender of their offspring. Gender selection is available all around the world but is illegal in certain

Mate selection Sexual Selection is a powerful evolutionary process, for those unable to attract or gain access to the opposite sex, risk being eliminated from the population (Apostolou). The theory of sexual selection was introduced by Charles Darwin in his book The Descent of Man, in which he explains, that selecting a mate is not a random process, and it is key to evolution, for it depends on which individuals have advantage over the rest of the same specie (Stanford 99). In sexual selection, males

In reading chapter forty it made me very angry, starting with sex-selection and the murder of children due to their gender. I acknowledge that many countries

parents with another opportunity: gender selection. It is now possible for people to select what gender their child will be. Though there may be some instances in which gender selection seems reasonable, altering the gender of a baby can begin a dangerous pathway for discrimination, gender imbalance, and parental acceptance. Gender selection is essentially made possible by the separation of male-producing sperm and female-producing sperm. “Gender Selection,” provided by Infobase Learning and Jackson

organism can mate. These factors include, but are not limited too: spatial separation of mates and resources, how long the specimen are sexually active/virile, does this species advocate parental care for their young, sex ratio and mate availability, and ultimately sexual selection. These factors will be discussed, broken down, and addressed in detail throughout the course of this paper. However, first we must ask the question, what exactly is a mating system? The term mating system refers to the

Along with being unique, they can be difficult and take work and dedication by both partners. The difficulties faced in these relationships can be attributed partially to the differences between men and women. Theses differences range from mate selection to attachment styles to the way in which problems are dealt with. First and foremost, differences between men and women can be seen in the stages leading up to a romantic relationship. Each individual has certain characteristics that they look

Beauty is in the eye of the beholder. But does perception of beauty change when and individual consumes alcohol? This age old question has been studies over the past decades to understand the consequences of alcohol consumption, gender and mate selection. In their research, Abbeele et al. aimed to explore the relationship of alcohol consumption and rating of attractiveness. The participants consisted of heterosexual social alcohol consumers that conducted an attractiveness-rating task. It was discovered

various human cultures and overwhelmingly occurs in countless animal species. In nonhuman primates, sexual coercion happens regularly and fairly consistently, leading scientists to presume sexual coercion tactics evolved as another form of sexual selection (Smuts and Smuts, 1993). However, difficulties arise when we try addressing human rape behavior, and with good reason. Sexual violence suffer deep psychological and physical trauma. Sexual violence victims severely underreport and rarely cases

when strong sexual selection led to the dissemination of the rival’s phenotype (Janif et al. 2014). Preference for an uncommon secondary sexual trait can bring negative frequency-dependent selection to bear the genetic variation among species. Previous studies have shown that rare traits have an advantage over other individuals from the same species, because it does intensify and promote the mating process. Humans have traits that can be manipulated to attract the opposite sex. For instance, males’
