Reproduction

(Abell et al., 2013). Similarly, fish have developed numerous social, reproductive, and predatory behaviours that make them well adapted to various conditions. For example, observing reproductive behaviours of hermaphroditic reef fishes found that reproduction methods are species dependant, though there are similarities and overlaps (Petersen, 1987). In a study of Serranus faciatus, Petersen (1987) found that all individuals have fully functional gonads of both sexes (simultaneous hermaphrodite)…

What many people realize and don’t understand is that being born with an Intersex condition is not easy as everyone thinks or sounds. People paint a picture of what an intersex person looks like and what their genitals looks like in their mind. Even people in the LGBT community often times paints a rosy picture of what life is like for an Intersex person. The reality is, that it’s not easy being an intersex person and it sure ain’t easy having to deal with your Intersex condition. Many people…

mosquitofish and perform a vertical life history analysis. Fish were captured and measured around Hennington pond at FIU, and data was compiled into a vertical life history table. This table revealed that the fish have relatively short life times and high reproduction rate,…

theory. Even though she is quiet eager to have her first child, she is not willing to push her beliefs aside in the process. Any kind of reproductive assistance may affect her beliefs. In the Natural law theory they believe that the process of reproduction must consist of a married couple engaging in sexual activities.…

Mexico. The lizard lives in two states, New Mexico and Arizona. The leaping lesbian lizard is the state reptile of New Mexico. The lizard has two different ways of reproduction. The lizard is a hybrid species between the little striped whiptail and the western whiptail. Females reproduce using parthenogenesis ( a type of asexual reproduction.) They also reproduce through hybridization. These two…

size, and population density, as these variable were positively correlated. Lifetime reproductive success was measured by how many offspring were produced by a wolf during its lifetime. Age of first reproduction was monitored and known for 52 males and 53 females. In account to the age of first reproduction, whether the individual had helpers or not and its mass and size were taken into…

notions about anthropology, I believed it was simply the study of cultures from a subjective manner, a very cut and dry study which would not take much elaborate thought. As classes progressed, particularly once we had moved onto the study of sex, reproduction and personhood, my understanding of the versatility of anthropology expanded greatly. I have realised that what I before thought was a static, uniform study is in fact more variable that I could have imagined. In this essay, I will explain…

The cane toad reproductive system especially of male consists of the fat bodies and this cannot be found in a reproductive system of a common brushtail possum. The process of how sperm travels is also different between the two animals. In a common brushtail possum, the sperm travels through the vasa deferentia, which transports the sperm from the epididymis to the urethra (Venugopal, 2016. pg 3.5). While in a cane toad the vasa efferentia helps carry the sperm from the testes to the kidney and…

Sexed Semen is changing the Face of Cattle Reproduction Worldwide Sexed Sorted Semen is still a relatively new reproductive technology that is impacting cattle producers and semen marketers worldwide. Using flow cytometry, purified sperm is sex sorted into X-bearing chromosome and Y-bearing chromosome populations. These subpopulations can then be frozen and stored for future use in artificial breeding. This technology works well in a well-managed artificial insemination or embryo transfer…

Fertility is the ability to produce children whereas infertility is the inability to produce children or to be able to carry a child to the end of the pregnancy or to delivery. Infertility is a very big problem amongst couples. According to The Columbia Encyclopedia, there are about forty percent of cases of infertility in men that have been reported and forty percent of cases of infertility in women that have been reported as well. There are some cases, about twenty percent, who have unknown…
