What is it called when replication is messed up?
Mutation occurs, if a mutation is recessive it is not expressed in the phenotype, if however it is dominant when passed on in the offspring it is expressed in the phenotype.
Which gene mutation is less likely to result in a phenotype change and why?
phylogeny
What is a backmutation?
A backmutation is a mutation in genetics which restores the original sequence and the original phenotype.
Which genotype will give rise to the Bombay phenotype?
The Bombay phenotype is caused by a homozygous recessive mutation in the FUT1 gene, which results in the absence of H antigen on red blood cells. Therefore, the genotype for the Bombay phenotype is hh.
Mutations in introns are less likely to affect phenotype then mutation in exons?
Mutations in introns are less likely to affect phenotype because introns are not translated into protein, unlike exons which contain coding regions for proteins. Introns are involved in regulation of gene expression through processes such as alternative splicing, but mutations within introns typically have a more subtle impact on gene expression compared to mutations in coding regions (exons).
