Rachael McAlister A&P II Extra Credit Paper J. Kamykowski 29 – November - 2011 Porphyria: The Vampire Disease Porphyrias are a hereditary group of disorders in which heme is not properly made. There are many different forms of this disorder‚ with porphyria cutanea tarda being the most common type. Remember what happens to Edward Cullen from the Twilight series when he gets out in the sun? Yea‚ me neither. But in classic movies and early folklore‚ vampires were commonly depicted as having purplish

To what extent does genetic inheritance influence behaviour? Use relevant research studies in your response. In this essay‚ I am going to be focusing on the influence of genetic inheritance on behaviour. Behavioural genetics deals with understanding how both genetics and the environment contribute to individual variations in human behaviour. Genetic arguments of behaviour are based on the principle of inheritance. Genes and their DNA are passed down from parents to their offspring. I will be reviewing

introduction Non-infectious diseases (also called Non-communicable diseases) are those diseases that are not caused by a pathogen and cannot be shared from one person to another. Disease caused by these organisms are infectious diseases. There are many kinds of non-infectious diseases. Non-infectious diseases may be caused by either the environment‚ nutritional deficiencies‚ lifestyle choices‚ or genetic inheritances. Unlike infectious diseases‚ non-infectious diseases are not communicable or contagious

A rare and fatal disease‚ Tay-Sachs is characterized as one of the devastating neurodegenerative disease. Children afflicted with Tay-Sachs “lose motor skills and mental functions” eventually becoming “blind‚ deaf‚ mentally retarded‚ paralyzed...Tay-Sachs children usually die by age five” (“Tay-Sachs Disease”). A diagnosis of infantile Tay-Sachs is akin to a death sentence; the only form of care would be comfort for death. Tay-Sachs is passed on genetically from parent to child and‚ as it is an autosomal

Chapter 15 The chromosomal basis of inheritance Key ideas: 1) Mendelian Inheritance has its physical basis in the behavior of chromosomes during sexual life-cycle. 2) Morgan traced a gene to a specific chromosome. 3) Linked genes tend to be inherited together because they are located on the same gene. 4) Independent assortment of chromosomes and crossing over produce genetic recombinants. 5) Geneticists use recombination data to map a chromosome’s genetic locus. 1900 Biology finally

Huntington’s disease is an inherited disease. Huntington disease results from altered activity of basal nuclei neurons. Basal nuclei neurons gradually deteriorate‚ resulting in unrestrained movement. Huntington’s disease has a extreme impact on a person’s functional abilities and usually results in movement‚ thinking and psychiatric disorders. Most people with Huntington’s disease will develop signs and symptoms in their 30s or 40s. But the disease can emerge earlier or later in life. If the disease develops

“To what extent does genetic inheritance influence behavior?” A debate of nature vs. nurture‚ as in whether it is our inherited genes or environmental factors that affect our behavior‚ has been going on for years. There are no true experiments on genetic inheritance influencing behavior due to ethical reasons. Only quasi-experiments and theories of pre-existing data are available that are on genetics or environmental factors affecting behavior. With the few studies existing one can still argue

made via pea plant experiments conducted by him over 1856 to 1863 that showed how certain traits are passed on to next generation. Over this time period he is said to have tested over 5000 pea plants and from this he derived the law of Mendelian Inheritance He was able to predict the probabilities of certain characteristics being passed onto the offspring of plants. He showed that certain factors‚ now known as genes‚ affected

Lev Vygotsky theory of child development is known as the socio-cultural perspective. He argued that children learn through social interactions with an adult or peers more experienced than them. Vygotsky socio-cultural perspective states that the way a child thinks when growing up improves when they work in their Zone of Proximal Development (ZPD). Zone of Proximal Development states that a child’s interaction with peers is an effective way of developing skills and strategies. Children are more likely
