Mating

Human mating is observed in almost every culture, leading us to the diverse world we live in today. This signifies our existence and should be important to us. To better understand this behavior, we can take a look at different explanations which shape human mating behavior. Researching this topic we can find evolutionary perspectives, which delve into topics, such as parental investment, survival, and sexual selection. There is also an opposition to these evolutionary ideas which suggest that evolution may not have to do much with our mating behavior, but is influenced but social norms and libidinous desires. This paper will try to look into these ideas and try to find a conclusive winner, or maybe we will find out that these theories all…

larger body size than that of males (Savalli & Fox, 1999). Despite their small size, males are known to have relatively large ejaculates, which act as a source of resources for their mates (Edvardsson, 2007). Although having access to these nutrients provided by their mates is of benefit to the females, it appears that living in the presence of males is costly to female C. maculatus health. Both females who were provided nutrients and those who were nutrient depleted had a shorter lifespan when…

This review article describes how the mating decision of Drosophila fruit flies is dependent of first the male’s choice to mate and then the female’s choice to accept or reject the male. The article simplifies the mating by the neurobiology behind the male’s choice and then the female’s choice. Furthermore, the article describes how males rely on chemical signals to detect suitable courtship objects and distinguish female flies from males. According to the article, males courtship is based on…

Eberhard. They use some of the behavioural anomalies in these species to look at how females affect paternity such as how females actively participate in creating copulatory plugs as well as physical clasping by the female rather than the male during copulation. They present evidence that female Leucage individuals have powerful effects on whether copulation will occur, when it will end, whether a mating plug will be formed and whether the male will survive the encounter arguing that several…

the problems it is causing in Hawaii. The effects the Coquí has on Hawaii and in Puerto Rico are viewed differently and creating many conservational issues that has arisen in both places. The Coquí genus is “Eleutherodactylus, which in Greek means free toes. As the name indicates, this (genus) has no inter digital membrane, which could indicate that they are not adapted to swim. All Coquí’s have disks or pads on the tips of their toes, to help them adhere to surfaces, like moistened…

choosing a mate appeared and had no choice but to choose someone whom they could trust would bring food on the table and security to her and their offspring. Moore and Cassidy think that “female reproductive success is therefore constrained by access to the resources necessary to raise costly offspring.” In order to seek for a mate, Puts tells us that women were competing to be the most attractive ones because more physically attractive women demand greater male investment and other direct and…

Kwon-Chung in 1976 has mentioned that C. neoformans exists as two mating types, MATa and MATα which is determined by single locus with diomorphic alleles.(Halliday CL et al, 1999). The MAT locus of C. neoformans is larger and consists of 100 kb having more than 20 conserved genes. These mating types play an important role in sexual development changes. These also play a vital role in epidemiology by knowing the prevalence and virulence of the isolate (Lengeler KB et al, 2000). Based on the…

The cyborg polar bear would then continue his mating with Arcus, ramming in and out of the black bear’s tail hole, each time his thrusting became faster and much more intense as he clamped his hands down on Arcus’s hips and continues. The cyborg inspector himself was now finding himself in an increasingly weird situation, his first day of arrival in Zootopia was marked by forceful anal sex with a crime boss so he can walk around freely in town! It’s just too ridiculous for him to bare. But he…

Love is one of these things that can grow deeper in time, where instead of the lust it’s a now emotional pull. “Many couples experience their relationship like dance in which great sex brings them close, but then this very closeness can make sex difficult again.” (“Mating in Captivity,” 2006, p.28) In chapter 2 Perel describes that love and desire are two different ideas completely. While we typically seem to think they are one in the same, they clash most of the time. Love can be nurturing,…

Illustration of sexduction in E. coli using streptomycin resistant F-lac- recipients and F′lac+ donors Abstract The process in which DNA from a donor cell is transferred through physical contact into a recipient cell is known as conjugation. In the experiment, sexduction, a cross between F′ and F- plasmids, was demonstrated by mixing the donor and recipient, diluting them and using selective plating methods. The plasmids from the donor, recipient and transconjugant were isolated and analyzed…
