Genetic Diversity In Helianthus Annuus: Selective Breeding And Induced Mutagenesis, Dillon Holton
Genetic Diversity In Helianthus Annuus: Selective Breeding And Induced Mutagenesis, Dillon Holton
Thinking Matters Symposium
H. annuus, more commonly known as the sunflower, is a single species that has many different variations. Traits have been selectively bred for hundreds of years in order to produce a beautiful flower as well as essential agricultural products. Recently interest in the sunflower as a food and fuel crop has led to selective breeding of seeds that produce high yields of sunflower oil. To further push the limits of this plant's genome, researchers have used mutagenesis to force mutations in hopes of developing novel modifications that could increase yield. With the entire genome mapped, the goal for many research …
Changes In Gene Sequence That Cause Discordances Involving Disease In Monozygotic Twins, Kacie Jacques
Changes In Gene Sequence That Cause Discordances Involving Disease In Monozygotic Twins, Kacie Jacques
Thinking Matters Symposium
Identical twins or, monozygotic twins, occur when the egg in a mother is fertilized, but one zygote divides into two separate embryos. Monozygotic twins are considered to be genetically identical, but most twins often display discordances, some involving diseases or disorders. Some of these differences are due to environmental factors. For example, one twin may have diabetes due to diet. Recent literature has shown that some differences in monozygotic twins may be due to changes in gene sequence, as opposed to random, environmental or epigenetic factors. Identical twins from pedigrees with familial disease often show discordances. When looking at schizophrenia …
The Evolution Of Mimicry; The Doublesex Gene, Aisha Hill
The Evolution Of Mimicry; The Doublesex Gene, Aisha Hill
Thinking Matters Symposium
Many butterfly species use mimicry in order to increase their chance of survival. In Batesian mimicry, non toxic butterflies mimic the wing patterns, colors, and shapes of another species that is toxic to predators. Swallowtail butterflies (Papilio polytes) are well-known Batesian mimics, and also display sexual dimorphism with distinct differences between the sexes. Sex limited mimicry is common. The female butterfly may mimic an inedible red-bodied swallowtail, such as the common rose (Pachliopta aristolochiae), or she may be non-mimetic. The male butterfly is non-mimetic. This is a review of recent research into the origin and evolution …
Understanding The Genetics Of Schizophrenia, Matthew Toohey
Understanding The Genetics Of Schizophrenia, Matthew Toohey
Thinking Matters Symposium
Schizophrenia has been considered heritable for a long time, but only with the advent of new technologies such as whole-genome sequencing and genome-wide association studies can we begin to identify specific molecular causes of schizophrenia. This poster will review some of the genetic variants that research groups have associated with schizophrenia. Current research has indicated that schizophrenia is a polygenic disease and has been linked to many genes. Some of these common risk variants are in protein coding sections of the DNA. These proteins are often linked to neurological development or immune system function. Other variants that have been associated …
Importance Of Understanding Genetic Predisposition, Andrew Carter
Importance Of Understanding Genetic Predisposition, Andrew Carter
Thinking Matters Symposium
Hypersensitivity reactions can be sudden and are often fatal. Many of these reactions occur as a result of allergies to prescribed medication. Adverse drug reactions or (ADR’s) were show in a recent study to affect over 6% of hospitalized patients and resulted in over 100,000 deaths a year in the US alone. This poster will review the importance of understanding genetic predisposition, through articles about possible genetic causes of allergies to penicillin and other beta-lactams. Changes in a specific HLA gene located on chromosome 6 showed a correlation to penicillin reactions in over 600,000 participants. Another study found a conclusive …
