Modeling Hybrid Novel Traits: A Case Study In Complex Petal Pigment Patterning In Hybrid Mimulus, Xingyu Zheng May 2020

Modeling Hybrid Novel Traits: A Case Study In Complex Petal Pigment Patterning In Hybrid Mimulus, Xingyu Zheng

Undergraduate Honors Theses

Hybridization between species, by introducing dramatic trait variation into the population and creating viable, transgressive offsprings with novel phenotypes, can have huge evolutionary implications. Some hybrid traits have been studied in the classical genetics or population genetics context, but most complex traits are determined by multiple causes, e.g. the number of loci involved, the rewiring of the genetic circuitries, and the changes in gene expression pattern. Using the hybrid monkeyflower petal pigment patterning as an example, we present a case study to investigate complex hybrid traits in a systematic manner that includes empirical data analysis and quantitative mathematical modeling of …


Search For Selection: Genomic, Transcriptomic, And Phenotypic Investigations Of Spotted Seatrout (Cynoscion Nebulosus), Jingwei Song Jan 2020

Search For Selection: Genomic, Transcriptomic, And Phenotypic Investigations Of Spotted Seatrout (Cynoscion Nebulosus), Jingwei Song

Dissertations, Theses, and Masters Projects

Climate change has resulted in both increased mean water temperature and higher frequencies of extreme water temperatures in coastal areas. These new thermal regimes exert strong selective pressure on the thermal physiology of coastal aquatic species. Phenotypic plasticity (the ability of one genotype to display multiple phenotypes) and local adaptation (increased fitness to local environment due to natural selection) dictate both short-term (from hours to days to weeks) and long-term (from years to decades) resilience of a species. To better predict how a species will respond to the negative impacts of climate change, one first needs to know the current …

An Assessment Of The Population Genetic Structure And Evidence Of Multiple Paternity In Channeled Whelk, Busycotypus Canaliculatus, Along The Us Atlantic Coast, Samantha E. Askin Jan 2020

An Assessment Of The Population Genetic Structure And Evidence Of Multiple Paternity In Channeled Whelk, Busycotypus Canaliculatus, Along The Us Atlantic Coast, Samantha E. Askin

Dissertations, Theses, and Masters Projects

Channeled whelk (Busycotypus canaliculatus Linnaeus, 1758) are predatory marine gastropods that are found in intertidal regions of the continental slope along the U.S. Atlantic coast from Cape Cod, Massachusetts to Cape Canaveral, Florida. The channeled whelk is a commercially important species that supports a fishery along the Atlantic coast of the United States. The resource is managed at the state level with minimum landing size (MLS) varying by state. Biological assessments of channeled whelk in the mid-Atlantic and Massachusetts have indicated that females have a low probability of being mature when they enter the fishery. The life history characteristics of …


Genetic And Morphological Assessment Of Population Structure Of The Clearnose Skate (Rostroraja Eglanteria) From The Western North Atlantic Ocean, Lindsey Noel Nelson Jan 2020

Genetic And Morphological Assessment Of Population Structure Of The Clearnose Skate (Rostroraja Eglanteria) From The Western North Atlantic Ocean, Lindsey Noel Nelson

Dissertations, Theses, and Masters Projects

The Clearnose Skate (Rostroraja eglanteria, Bosc 1800) is a flat, benthic elasmobranch and member of the family Rajidae. They are widely distributed in the coastal waters of the east coast of the United States and in the northeastern Gulf of Mexico. It has been noted that the physical appearance of Clearnose Skate from the southern end of their range near South Carolina is distinct from individuals found in the northern end of their range near Woods Hole, MA, perhaps suggestive of a sub-species, though this observation has not been further investigated. Clearnose Skate are seasonally migratory and are often incidentally …
