Evolutionary genetics: What is driving male mutation?
نویسنده
چکیده
In mammals, most new mutations occur in males. But a study of the evolution of a human X to Y chromosomal translocation has revealed a sex bias much lower than previous estimates. Patterns of substitution suggest that differential methylation between male and female germ lines is a key determinant of the mutation rate.

A general population genetic framework for antagonistic selection that accounts for demography and recurrent mutation.
Antagonistic selection--where alleles at a locus have opposing effects on male and female fitness ("sexual antagonism") or between components of fitness ("antagonistic pleiotropy")--might play an important role in maintaining population genetic variation and in driving phylogenetic and genomic patterns of sexual dimorphism and life-history evolution. While prior theory has thoroughly characteri...

Investigation of Method of Fulfillment of Civil and Criminal Responsibility in Case of Intervention in Changing Human Genetics
Therapeutic needs and the advancement of medical technology occasionally cause people to be willingly or unwittingly in a position that their genetic structures in their bodies change. The ultimate goal of this study is to determine. Whenever a gene is damaged how this damage can be assessed and if we prove responsible for the damage to the gene, what is the type of liability of natural and leg...

Background The X-linked cyclin-dependent kinase like 5 (CDKL5/STK9) gene has been shown to be responsible for a severe encephalopathy condition characterized by early onset of epilepsy and severe developmental delay. CDKL5 mutations have been shown to be more frequent among female patients. Results Here we report a 6- month male patient, second child of a healthy non consanguineous in the Irani...
متن کاملA Novel Missense Mutation in CLCN1 Gene in a Family with Autosomal Recessive Congenital Myotonia
Congenital recessive myotonia is a rare genetic disorder caused by mutations in CLCN1, which codes for the main skeletal muscle chloride channel ClC-1. More than 120 mutations have been found in this gene. The main feature of this disorder is muscle membrane hyperexcitability. Here, we report a 59-year male patient suffering from congenital myotonia. He had transient generalized myotonia, which...
