In Mendelian inheritance patterns, you receive one version of a gene, called an allele, from each parent. These alleles can be dominant or recessive. Non-Mendelian genetics don’t completely follow ...

In the first study of its kind, scientists have detected evidence that DNA may not be the only carrier of heritable information; a secondary molecular mechanism called epigenetics may also account for ...

The concept of epigenetic inheritance has long been controversial. Some researchers hope that new data on cross-generational effects of environmental exposures will help settle the debate. Andrea ...

Parental behavioural traits can be transmitted by non-genetic mechanisms to the offspring. Although trait transmission via sperm has been extensively researched, epidemiological studies indicate the ...

Dermatoglyphic traits in a sample of twins were analyzed to estimate the resemblance between MZ and DZ twins and to evaluate the mode of inheritance by using the maximum likelihood-based Variance ...

V.Q.R. da Silva, A.T. Amaral Júnior, C.A. Scapim, S.P. Freitas Júnior and L.S.A. Gonçalves When using genotypes of different heterotic groups, the scarcity of information on the inheritance of traits ...

Genetics is fiendishly complex. We know this from decades of molecular biology, from the resulting studies on the sequencing and analysis of genomes and from our increasing knowledge of how genes ...
