Dr. Abraham Tucker
Chair / Associate Professor of Biology / Embree Professorship
Slot Number: 14
Abe Tucker is chair of the Department of Biology and Associate Professor of Biology and an evolutionary geneticist. After completing a B.S. in Biology at University of Southern Maine (2003), he completed his Ph.D. in Genetics at University of New Hampshire (2009), and was a postdoctoral scientist at Indiana University (2009-2013). Dr. Tucker’s research interests include comparative and population genomic approaches to understanding the forces of genome evolution (e.g., mutation, selection, drift, recombination, and population structure) in different ecological and population-genetic environments. His studies have described the genomic implications for the evolution of asexuality (i.e., loss of recombination), as well as the evolution of mutation rates. In Dr. Tucker’s lab at SAU, students can gain experience in a number of research areas including field collection of organisms, live-culture maintenance, molecular biology lab work, and bioinformatic analysis of genetic/genomic data. He currently teaches Genetics, Evolutionary Biology, Molecular Biology, Principles of Biology I, Viral Genetics, and Genome Evolution.

New Species of Mutant All-Female Crayfish are Taking Over!
Since the sequencing of the neandertal genome and subsequent additional archaic genomes, evidence of neandertal introgession (hybridization and backcrossing) has been found in nearly all non-african human genomes studied to date. For instance, I am ~2% neandertal and the distribution of neandertal alleles across current human genomes is scattered across all 22 autosomes. For instance, here
Daphnia mutation paper published in Genome Research
Abstract: Knowledge of the genome-wide rate and spectrum of mutations is necessary to understand the origin of disease and the genetic variation driving all evolutionary processes. Here, we provide a genome-wide analysis of the rate and spectrum of mutations obtained in two Daphnia pulex genotypes via separate mutation-accumulation (MA) experiments. Unlike most MA studies that
