Breeding

consumer. Many of the foods that are already common in our diet are obtained from plant varieties that were developed using conventional genetic techniques of breeding and selection. Hybrid corn, nectarines which are genetically altered peaches, and tangelos which are a genetic hybrid of a tangerine and grapefruit are all examples of such breeding and selection. Bioengineered foods and food ingredients including food additives must adhere to the same standards of safety under the act that apply…

is between true breeding (both parents are homozygous and one is homozygous dominant, while the other is homozygous recessive), and the offspring is heterozygous. The phenotype of both parents are present in the offspring. An example of codominance is if a white flower (rr) and a red flower (RR) breed to produce an offspring (Rr), whose phenotype is red and white stripes, therefore showing that both parents’ phenotype is present. Incomplete dominance is also between true breeding, and the…

Lentils - Disease Prevention Breakthrough A major breakthrough has been made by a PhD student in prevention of selenium – a micronutrient and mineral deficiency in humans. Selenium is linked to probable incidences of certain diseases including male infertility, heart diseases, viral infections and some cancers. Globally, over one billion individuals have selenium deficiency as a result of poor diet and majority of them are from countries like Bangladesh, New Zealand and Australia where levels…

Among lizards there are carnivorous, herbivorous and omnivorous species. Herbivorous lizards recommended to feed a variety of vegetables and fruits. These animals are happy to eat the cabbage, carrots, lettuce, apples, etc. All the products are fed lizards must be previously well washed. It should be carefully monitored to ensure that fruits, vegetables and herbs are environmentally friendly, in any case should not be given to animals, plants treated with chemicals or grown near highways.…

Todays’ society has led to the demise of the original reputation of the Pit bull. False allegations and intentional implantation of fear has contributed to the degradation of this breed. For the past several years, the Pit bull has had their reputation demolished due to false assumptions. However, the Pit bull was not always an object of discrimination. Within the last decade, society’s view of this beloved breed has degenerated. Quite often, the Pit bull is no longer looked upon as a…

For example a potato contains glycoalkaloid and there are recorded incidents of human poisoning. Celery contains a natural chemical that turns toxic when exposed to sunlight. “So, the normal kind of breeding can produce risks, just as any other genetic or other kinds of breeding can produce risks.” [Hotchkiss] This is why we must use a common sense approach to labeling. We cannot label everything. Additives that are toxic or known allergens are prohibited and prohibited ingredients would…

part of natural selection further support these four postulates and are recognizable examples in real life. Darwin describes artificial selection on page 3 as “picking out individuals with any desire quality and breeding from them…”. This overlaps with the pigeon and dog breeding in breeding example (artificial selection) as discussed in class. For example, even today sexual selection is evident in many tropical bird species due to the differential success in mating due to varying…

The practice of agriculture is becoming a serious problem, especially considering with the world’s population estimated to increase from 7.2 billion to 9.6 billion (un.org, 2013). There is already not enough food that can be distributed to sustain the already 7.2 billion people existing on this planet. The source of the solution lies in the hands of the growers of our food and the agricultural industry. The industry is stuck in very traditional ways that have vast room for improvement in yield…

Animals Behind Bars Chances are if a person has swam with dolphins, fed a giraffe, or interacted with a whale, they were visiting a zoo or aquarium (Hulick 1). Children that are involved in these activities are often jubilant and engrossed by tons of animals as they stroll through zoos all around the world. What they are not aware of is that these animals are not elated or healthy being restrained in these zoos. Circuses, zoos, and other sanctuaries harm animals just to entertain people around…
