The human genome, for example, contains over 3.1 billion ... the result of a mutation. The new genetic variant (allele) spreads via reproduction, and differential reproduction is a defining ...

cells favored one allele or the other, exhibiting what the authors call random allelic expression (RAE). These genes are more likely to acquire harmful mutations, the authors say, and therefore, could ...

Mutations are the only source of new alleles. Some people carry a mutated version of the gene that codes for haemoglobin. The protein that is coded for by the mutant allele doesn’t function ...

How could a "bad" gene-- the mutation that causes the sometimes lethal ... This situation is a stark example of genetic compromise, or an evolutionary "trade-off." ...

This includes which allele (if either ... along with the diploid genotype associated with each ID number. For example, if the first individual has the AB/ab genotype, this genotype will be ...
