Forward genetics provides researchers with the ability to identify genetic changes caused by mutations that are responsible for individual phenotypes in organisms. [1] There are three major steps involved with the process of forward genetics which includes: making random mutations, selecting the phenotype or trait of interest, and identifying ...
Gene redundancy is the existence of multiple genes in the genome of an organism that perform the same function. Gene redundancy can result from gene duplication . [ 1 ] Such duplication events are responsible for many sets of paralogous genes. [ 1 ]
The main source of genetic redundancy is the process of gene duplication which generates multiplicity in gene copy number. A second and less frequent source of genetic redundancy are convergent evolutionary processes leading to genes that are close in function but unrelated in sequence (Galperin, Walker & Koonin 1998). Genetic redundancy is ...
Forward genetics (or a forward genetic screen) starts with a phenotype and then attempts to identify the causative mutation and thus gene(s) responsible for the phenotype. For instance, the famous screen by Christiane Nüsslein-Volhard and Eric Wieschaus mutagenized fruit flies and then set out to find the genes causing the observed mutant ...
Minimum redundancy feature selection is an algorithm frequently used in a method to accurately identify characteristics of genes and phenotypes and narrow down their relevance and is usually described in its pairing with relevant feature selection as Minimum Redundancy Maximum Relevance (mRMR).
Mesquite is software for evolutionary biology, designed to help biologists analyze comparative data about organisms. Its emphasis is on phylogenetic analysis, but some of its modules concern comparative analyses or population genetics, while others do non-phylogenetic multivariate analysis.
REAL is an efficient, accurate, and sensitive tool for aligning short reads obtained from next-generation sequencing. The programme can handle an enormous amount of single-end reads generated by the next-generation Illumina/Solexa Genome Analyzer. cREAL is a simple extension of REAL for aligning short reads obtained from next-generation ...
FASDA (Fast And Simple Differential Analysis) is a fast and memory-efficient differential analysis tool written in C, following object-oriented design and strict code-quality practices. It takes SAM/BAM/CRAM or kallisto abundance files directly as input, and produces fold-changes and exact P-values for up to 5 replicates, near-exact P-values ...
