Mendelian inheritance

Gregor Mendel, a botanist from the IX century, was the first scientist to study inheritance patterns of traits using peas and other plants. After several years of experiments and data collection, Mendel came up with two important principles of inheritance that we consider essential to understand our modern genetics. The first principle is called the law of segregation, which states that the two alleles of a gene segregate from each other during the process of meiosis. Meaning that some gametes…

asecondary goal in conductingathis lab was to study and comprehend mendelian genetics. In this experiment, Drosophilaamelanogaster, commonlyaknown as fruit flies, were used to studyaand understand the principles of mendelianagenetics. D. melanogasterawas also used as a model to identifyathe patterns of inheritance of certainamutant traits in fruit flies. Mendel’salaw ofasegregation is important in understandingagenetic inheritance. It statesathat each pair of homologousatrait carrying particles…

one to six nucleotides that are interspersed throughout the genome. Microsatellite also known as simple sequence repeats (SSRs) or simple sequence length polymorphism (SSLPs) (Dhar et al., 1988). SSRs are inherently unstable and are inherited in a Mendelian manner (Jarne and Lagoda, 1996). They are highly abundant in eukaryotes, prokaryotes and even small bacterial genomes. SSRs can be found anywhere in the genome both in coding and non-coding region and may be arise through an error in the…

Father of modern genetics, Gregor Mendel, is well known for his garden pea plant experiment in which he discovered the phenomenon of “dominant” and “recessive” traits (Orel, 1996). His experiments led him to what is known as today’s Mendel’s Laws of Inheritance: Law of Segregation, Law of Independent Assortment, and Law of Dominance (Orel, 1996). The Law of Segregation states two alleles for a heritable character separate from each other during gamete formation and end up in different gametes…

evolutionary thought. Today, the evolutionary theory combines the “original” Modern Synthesis with an understanding of DNA along with cellular chemistry. The following three subjects are very critical to be able to understand evolution: natural selection, Mendelian genetics, and DNA. The modern evolutionary synthesis explains how the discoveries of Gregor Mendel go hand in hand with that of Charles Darwin. The discovery of evolutionary principles first took place in western Europe. The…

several characteristics that make them excellent subjects for genetic studies. Gregor Mendel was born 1822, and he is known as “Father of Genetics”. He initially studied the inheritance of just one pair of contrasting traits. Mendel begins his experiment with…

The Cold Spring Harbor Laboratory, in Laurel Hollow, New York, is now one of the première non-profit, biological research institutes, specializing in cancer, quantitative biology, neuroscience, and genomics. It has advanced from a school that primarily trained high school and college teachers, to a key developer in molecular genetics and biology, as well as an institution that emphasizes educating the new generation of scientists and the public. According to the Cold Spring Harbor Laboratory…

Tongue-Tastic Rolling For my pedigree project I did tongue rolling. My dad can roll his tongue but my mom on the other hand can’t. In conclusion to my project I figured out that a lot on my dad’s side could roll their tongues, such as almost all my aunts and one uncle. The only ones who couldn’t are my Aunt Rachel and Aunt Becky. On my mom’s side only my Uncle Scott can. I also learned that my brothers and I can all roll our tongues, which is pretty cool. I can use this in the future to figure…

In biology, evolution is the change in the characteristics of a species over several generations. The theory of evolution was developed by the naturalist Charles Darwin. Evolution relies on the process of natural selection, another thing discovered by Darwin. The theory of evolution is based on the idea that all species are related and gradually change over time. Desirable traits are the traits that help an organism survive. The organisms that have traits that help them live are able to pass…
