Mendel’s principle of inheritance Principle of segregation Two alleles per offspring, one from each parent Independent assortment Distribution of one pair of alleles does not influence another pair Genes don’t blend Eukaryotic and prokaryotic Prokaryotic – are one celled organisms. Two kinds- bacteria and archaea Cells structure is simple Eukaryotes- every organism that has more than one cell. Cell structure is more complex than prokaryotes Prokaryotes Prokaryotic cells are one celled

development while others are against the claim. The argument that cultural environment influence the lifespan development of an individual more than genes is true as it is argued that culture is an evolution which is a process that is very different from genetic evolution by natural selection, and it is playing the central role in the production of people’s behavior (Guest, A.M 2011). Genes does not dictate how development will go what they do is that they participate together with the environmental influences

Over the years, many studies have been conducted in order to answer the question if a person’s genetic makeup and environmental factors contribute to behavioral issues. This is an example of the nature vs. nurture debate. Nature has to do with the genetics while nurture has to do with environmental factors (Plomin, et al, 1994). An individual’s genetic code is made up of 46 chromosomes, 23 from each parent. It can be argued that an individual can be pre-disposed to violent tendencies and

mapping the human genome. The sequencing of the human genome is the largest undertaking in biological science, and is a huge achievement in the scientific community. The project was completed in 2003 and gave scientists the ability to read nature’s genetic blueprint of a human being. Those scientists and medical professionals who were excited about the HGP saw clearly how genomics would advance medicine. Genomic findings have advanced the diagnosis and treatment of many diseases. “Already, doctors

FXS can lead to a range of social and cognitive impairments, and it is one of the most frequent genetic causes of intellectual disabilities (Bagni, Tassone, Neri, & Hagerman, 2012). Individuals with FXS tend to exhibit hyperactive traits, attention deficits, language development difficulties, communication problems, visual-spatial processing deficits, and social anxiety (Reiss & Hall, 2007). Behavioral symptoms may include aggression, tantrums, self-injury, and repetitive behaviors (Newman, Leader

everything the body needs, especially proteins (Kugler, 2014). Our genes are passed down to us from our parents, having two copies of each gene. Those genes are found in the different strands in our DNA, which is what makes everyone’s DNA is unique. Behavioral genetics examine the role that our genes play in our behavior. The impact of heredity (nature) is the physical looks and characteristics passed down (inherited) from our biological parents. Heredity includes someone’s height, skin color and health

The significance of studying genetics and behaviour of flies or other organisms is that it would be used to understand other complex animals such as humans. “almost 75% of genes responsible for human diseases are observed to have homologs in Drosophila fly” (Pandey, U. B., & Nichols, C. D. ,2011). Moreover, one of the most available and favourable animal model used to study is the fruit Drosophila melanogaster. “Drosophila has been a key experimental subject in genetics since the early 1900s. It was

In a section of Ethics: Theory and Practice entitled “Biological and Genetic Determinism” Thiroux and Krasemann explain: “Biological determinism is best exemplified by Charles Darwin’s theory of natural selection, which he presented in his most famous work, The Origin of Species. Darwin (1809-1882) believed that various species in nature evolve at different stages in the history of the world and that only the fittest survive. For example, even though some prehistoric animals (I.e. dinosaurs) were

variant of the monoamine oxidase A (MAOA) gene which apparently predisposes an individual to disproportionate violence under any condition that triggers the carrier of that gene sequence to violence. As referred to in Mobley v State, "a possible genetic basis for violent and impulsive behavior in certain individuals." Also known as the rage gene and even more commonly, the warrior gene because of the theory that persons with this gene would likely have been the most efficient: berserk warriors on

IQ and Heritability According to studies conducted by researchers, it has been shown that genetic factors affect the IQ of a person, and specific genes that take part in influencing the IQ have been identified. The studies have also proposed that performance is affected by genetic factors. However, it has not been clear whether the genes that shape the IQ are the same genes that influence test scores and grades. The high heritability of intelligence proves to be a difficult subject because it may
