Mendelian inheritance

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…

Introduction This experiment was designed to examine inheritance patterns in Drosophila melanogaster. Three crosses were set up to examine the inheritance of eye color, body color, and wing shape. The mutant males used in this experiment had: sepia eyes with ebony bodies, white eyes and yellow bodies, or sepia eyes with vestigial wings. All of the females were wild-type. It was also confirmed that the females being used were virgins. This fact was important since female flies can store the…

non-genetic factors like environmental conditions. These traits are subsequent distributions of varying phenotypes that vary widely among individuals. Probably the main reason quantitative traits are considered complex is because they can’t be analyzed as Mendelian traits. So, quantitative traits won 't yield precise results as Mendel 'simpler traits because a quantitative trait will not be influenced by one gene alone. So, the fact that more than one gene govern quantitative traits (traits that…

Throughout several generations Darwinism has been applied to several concepts, and people continue to expand on it everyday. Darwinism is merely just the evolution of species through natural selection, which was developed through Charles Darwin. Darwin did many tests and studies to advance and add on to many theories discovered by other scientists, but all of the theories discovered by other scientists just go under Darwinism. Darwin did not come up with every theory that is a part of Darwinism,…

a science by using agricultural breeding. Instead of looking at the pea plant as a whole, Mendel focused on its individual traits. Mendel concluded that each alternative form of a trait is specified by alternative forms of a gene. To follow the inheritance of genes from parent to child, Mendel first needed to be sure which genes each parent carried. Mendel reasoned that pure-bred plants must have two copies of the same gene for each trait. Pure-bred pea plants when crossed did not produce…

25 degrees Celsius, and yields a large amount of offspring. This results in large amounts of data over a short time period. In this lab, the purpose was to demonstrate how the Drosophila melanogaster is used in the field of genetics to study the inheritance of traits throughout the F1 and F2 generations. Drosophila melanogaster was introduced into the wild type and other mutant alleles such as white eyed, vestigial, and sepia. The results gathered in the lab would then be compared to actual…

Title : Drosophila melanogaster Sexual Inheritance Patterns Introduction: This experiment determines sexual inheritance patterns amongst drosophila melanogaster. The model species drosophila melanogaster was used to study the passing of genes from one generation to the next. These fruit flies are good model species because the birth and generation process happens very quickly comparatively. One generation of a fruit fly lasts approximately 10-14 days. Several different traits were chosen to…
