Alleles are two or more alternative forms of a gene that arise by mutation and are located at the same place on a chromosome. It is of various types like lethal alleles, multiple alleles, etc. Answer and Explanation: When there are more than two al...

What are lethal alleles in the gene pool? Alleles: Alleles are the various copies of a gene that one can inherit from each parent. Most organisms have two copies of each gene, allowing for one allele from the mother and one allele from the father. The expression of these genes depends on...
Caruccio L, Bettinotti M, Director-Myska AE, Arthur DC, Stroncek D (2006) The gene overexpressed in polycythemia rubra vera, PRV-1, and the gene encoding a neutrophil alloantigen, NB1, are alleles of a single gene, CD177, in chromosome band 19q13.31. Transfusion 46:441–447...

Genetic polymorphisms in the APOE ɛ and TOMM40 ‘523’ poly-T repeat gene loci have been associated with significantly increased risk of Alzheimer’s disease. This study investigated the independent effects of these polymorphisms on human cognitive ag
To determine whether allele-product instability could explain failure to identify some mutations, we analyzed polymorphic variants in the COL5A1 gene in 16 individuals, and we examined mRNA for the expression of both alleles and for alterations in splicing. We found a splice-site mutation in a ...
