Benjamin Crawford Pierce is the Henry Salvatori Professor [1] of computer science at the University of Pennsylvania. Pierce joined Penn in 1998 from Indiana University and held research positions at the University of Cambridge and the University of Edinburgh. He received his Ph.D. from Carnegie Mellon University in 1991.
The general selection model (GSM) is a model of population genetics that describes how a population's allele frequencies will change when acted upon by natural selection. [ 1 ] [ better source needed ]
A refractory gene alone would not have higher fitness than the native genes, but engineered underdominance may prove effective as a mechanism to spread such a gene. In this model, two genetics constructs are introduced into two non-homologous chromosomes. Each construct is lethal when expressed individually but can be suppressed by the other ...
In clinical genetics, consanguinity is defined as a union between two individuals who are related as second cousins or closer, with the inbreeding coefficient (F) equal or higher than 0.0156, where (F) represents the proportion of genetic loci at which the child of a consanguineous couple might inherit identical gene copies from both parents.

Types and Programming Languages, ISBN 0-262-16209-1, is a book by Benjamin C. Pierce on type systems published in 2002. A review by Frank Pfenning called it "probably the single most important book in the area of programming languages in recent years."
A monohybrid cross is a cross between two organisms with different variations at one genetic locus of interest. [1] [2] The character(s) being studied in a monohybrid cross are governed by two or multiple variations for a single location of a gene.

Developing software for pattern recognition is a major topic in genetics, molecular biology, and bioinformatics.Specific sequence motifs can function as regulatory sequences controlling biosynthesis, or as signal sequences that direct a molecule to a specific site within the cell or regulate its maturation.
