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 ...

Environmental factors can lead to heritable non-genetic changes in the mammalian germ line that affect behaviour in the offspring across several generations. These changes influence behaviours related ...

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 ...

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 ...

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 ...

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 ...

Some Juneau friends planted holly bushes in their front yard a few years ago. Those bushes grew well, producing dark green leaves with smooth edges. However, during a few winters of heavy snow, deer ...
