Further Description Of Hybridization In The Sea Stars Asterias Rubens And Asterias Forbesi Through The Application Of Species-Specific Genetic Markers, Callie Bateson
Honors Program Theses
Hybridization occurs when two separate species reproduce to form hybrid offspring. If the hybrid offspring backcross with individuals of their parental species, the subsequent offspring may have varying amounts of the parental genomes, if viable. Following the retreat of the Last Glacial Maxima 20,000 years ago, two sea star species, Asterias forbesi and A. rubens came into secondary contact in the Gulf of Maine where they began to hybridize. Previous research in our lab studied the frequency of hybridization at four locations along the east coast (Quebec, Nova Scotia, New Hampshire, and New York) using morphological identifications as well two …

Primer Efficacy In The Dna Barcoding Of Spiders, Rhennetta Jo Bork
Honors Program Theses
DNA barcoding is the process of amplifying a 650 base pair segment of the sequence of the mitochondrial gene cytochrome c oxidase (COI), and amplifying this gene with a polymerase chain reaction (PCR). It is used to help identify and distinguish animal species and also to help determine genetic differences in species. DNA barcoding can be especially useful when working with spiders since they tend to be very small and hard to distinguish. However, achieving a DNA barcode can be difficult and thus techniques to improve the method of DNA barcoding can be helpful. This research looked into the different …
