Imprinting

Epigenome compounds are bunches of chemical compounds that tell the genome what to do. They can turn genes on or off and control the production of proteins. The epigenome controls changes to the genome. It is made of chemical compounds. Some of the compounds are from manmade materials. Parents pass the genome to their children and during the passing of the epigenome, it is reset. The epigenome can change throughout a lifetime. Many factors can change it such as: smoking and diet. Epigenomes…

If both parents have alcoholism, will their children have alcoholism, too (nature vs nurture)? If both parents have alcoholism, it does not necessarily mean that their children will have alcoholism. Inherited biochemistry affects alcohol metabolism. There is no specific gene for alcoholism. However, the alleles that make alcoholism have been identified on every chromosome except the Y. Each individual is different, they're reaction to alcohol may be different from others. Both parents metabolism…

When baby animals such as ducklings are born, they begin to identify and follow their mother around through a process called imprinting. Scientists say a duckling can imprint on its mother in as little as 15 minutes after it is hatched. Once imprinting has occurred, the duckling can follow any object, be it the mother duck or any animal, provided that it sees the object within the typical "sensitive period." the study found that ducklings are capable of abstract thought. This newly discovered…

The Behaviourist approach assumes that: • All behaviours are learnt from the environment which means it ignores biological influences or freewill therefore making it a nature approach. • It assumes that all behaviours are automatically caused by response to stimulus such as in the case of Pavlov’s dog experiment where food being the stimulus and saliva being the response thereby creating the link between Response and Stimulus. • It also assumes that our behaviours are determined by…

syndrome is a genomic imprinting disorder caused by the failure to express SNRPN (small nuclear ribonucleoprotein-associated polypeptide N) gene product. SNRPN is expressed only on the paternal chromosome 15q11-q13, however, the exact genes responsible for Prader-Willi syndrome haven't been identified. People normally inherit one copy of chromosome 15 from each parent. Some genes are active only on the copy that is inherited from a person's father, the paternal copy. Genomic imprinting causes…

This was a huge discovery for Darwin because now we know that species are not fixed and are changing. Ethology, the study of animals in their natural environments, also played a role in the development of Darwin’s theory. Konrad Lorenz’s geese imprinting experiment demonstrated that evolution has a way of helping species survive in their environment. Darwin’s theory is a process that explains adaptation and speciation in a simple way. First, there is some sort of overpopulation in the…

John Bowlby was born in London on February 26, 1907. He came from an upper middle class family, was one of six children, and, as was common at the time, was raised by a nanny. His father was a surgeon, who at one time acted as a doctor to the king 's household. His father served in World War I, and was knighted for his service to the king. Bowlby never developed a close relationship with either of his parents. When Bowlby attended university, he demonstrated an aptitude for academics. He…

The nature versus nurture argument is, and has been, one of the most hotly debated topics in modern science for decades. The argument of whether humans start out as a “blank slate” or Tabula Rasa, as opposed to being predisposed with certain environmental effects out of their control transcends even natural science and enters into the realms of philosophy and psychology. It is nearly undeniable that the ideas of Mendelian inheritance are sound theories, yet the argument for…

Ethology, the study of animals in their natural environments, also played a role in the development of Darwin’s theory. Konrad Lorenz’s geese imprinting experiment demonstrated that evolution has a way of helping species survive in their environment. Intelligence testing became huge in America after Lewis Terman revised and expanded the Stanford-Binet Intelligence scales. This test tested the I…

In order to show emotion surely you must feel and have emotions, must you not? For instance, if you were to show empathy towards another human it would be declared that you can feel emotion as a consequence of having emotions, would it not? So why is this not that the case regarding animals’ emotions? As Flintoff states, animals show empathy, joy, fear, grief; the list is endless ‘they have a very rich ensemble of emotions’; why is this ignored by many? Out of convenience? Or perhaps because…
