Download file to see previous pages Polygyny is one of the types of breeding in animals which can be described by having a male member of the population have a specific or non-specific number of female partners. The said process can be considered of interest specifically in behavioural ecology in relation to the determination of different concept such as genetic contribution of parents, paternity, breeding behaviours and techniques and other issues that can help classify, observe and analyze the animals belonging to different groups and families (Scheffer, 1969; Sumich & Sumich, 2008). Included in the most significant examples of animals that utilize polygyny are the mammals. Based on the studies that had been undertaken related to the polygyny in mammals, one of the most important reasons for the said practice and/or adaptation is the unequal production of the gametes from the female compared to the male members of the population. The main role of the males in the population is to mate with a number of females regardless of the percentage the said number of females can achieve pregnancy in a particular breeding season. Due to the said behaviour of the male population, the females can also have different partners but fertilization and pregnancy can be achieved by a single male member of the population (Sumich & Sumich, 2008). There are different factors that can be related to the polygyny in mammals. Aside from the disparity in the gametes, sexual dimorphism is also another important indication of polygyny in selected species. ...Download file to see next pagesRead More

...chromosomal portions from any side of the parent. But during crossing-over, different parts are exchanged between pairs of chromosomes resulting in genetic variations. As a result every offspring has a different genetic make-up excluding identical twins. There are certain limitations applied to the Mendelian Laws which includes that they do not hold true for all living things. Only organisms participating in sexual reproduction and holding diploid chromosomes can be considered for these laws. Hence the laws cannot be applied to bacteria and other asexually reproducing plants and animals. Punnett Square Punnett Square was originally designed by Reginald C. Punnett.

Extreme Negotiations

...? Extreme negotiations High ranked officials in an organization or a department practice extreme negotiations in order to reach an agreement with a client in the best way without coercion.

Reproduction problems

...? [Teacher’s Reproduction problems Case The patient has a deficiency in the enzyme 21B hydroxylase which is responsiblefor the biosynthesis of corticosteroids which include cortisol and aldosterone. The enzyme is found in the gene CYP21A2. The deficiency of this hormone ultimately affects adrenal glands and is of congenital etiology. This pathological defect is responsible for the cause of congenital adrenal hyperplasia. The disease is autosomal recessive and leads to the impairment of cortisol synthesis, which takes place in the cortex of the adrenal gland. In the case of this patient the deficiency of 21 Hydroxylase led to the over production of androgen in the adrenal gland, which caused virilence in the patient. The exact... [Teacher’s...

...Breeding Thoroughbred Racing Horses Thoroughbred horses are a breed which was developed to have the ability to carry weight over long distances withsustained speed. The breed was originally developed in the 17th century when English mares were crossed with Arabian stallions. This followed an intensive breeding of the stock which resulted in successive generations of excellent race horses over a period of three centuries. All modern thoroughbreds are descendants of three horses named after their owners as the Darley Arabian, Godolphin Arabian and the Byerly Turk ( Breeding of thoroughbred horses is a highly intricate and technical matter...

...Balanced hormonal activity is not only crucial for maintaining pregnancy but also affects labor and post-labor changes in the maternal body. The hormone-oxytocin plays a very important role during parturition and lactation. The role played by the hormone during birth is still controversial. Mammalian studies suggest that “neurohypophysical oxytocin plays a role in the expulsive phase” (Blanks & Thornton, 2003) and also initiates parturition. All throughout pregnancy, progesterone plays an important role in sustaining it; however at the end of pregnancy, maternal estrogen rises simultaneously along with progesterone level. Estrogen induces oxytocin receptors in the uterine musculature while progesterone softens the cervix... hormonal...

However, people have different innate characteristics. People who are often involved in extreme sports tend to have a lot of adrenaline and their participation into such activities give the fulfillment. Interestingly, when these individuals have conquered a particular extreme activity, they get motivated to attempt to accomplish a more difficult activity than that which has been conquered.

Extreme sports

...Extreme Sports and Personal Responsibility Extreme Sports and Personal Responsibility It is abit surprising that some individuals submit themselves to participate in hazardous or extreme sports. Hatfield (2011) explains that the innate characteristics in some individuals dictate that they have to be turned on by such extreme activities since they have a lot of adrenaline that directs them towards such activities which they perceive fulfilling. Amazingly, when these individuals conquer in one of the extreme activities, they develop the desire to even conquer more extreme ones beyond the ones already conquered. Hatfield (2011) argues that...

...Reproduction Reproduction Reproduction is an important process in any living things. It helps in sustaining life as well as perpetuating life. In human, the organs of male and female are responsible for this work. They help in sexual reproduction through creating, nourishing, and accommodating sex cells also known as gametes (Palladino, n.d.). The paper will focus on the process of spermatogenesis in the male’s testis as well as oogenesis in the female. The process of spermatogenesis is a complex thing that takes place in the male. The male reproductive system comprises of a complex interaction. It has gonads also known as testes, a chain of ducts that helps in transportation of spermatozoa, and accessory glands (Palladino, n.d... is at its...
