The genetic bases of the seven pairs of contrasting traits in the garden pea that were described by the ‘father of genetics’, Gregor Mendel, have long puzzled scientists. The discovery of the genetic ...

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 ...

All of the different plants on Earth—from mango trees to marigolds—have come about thanks to the simple rules of genetic inheritance, which determine how traits are passed on from one generation to ...

Rett syndrome is a rare developmental disorder, most often due to a mutation in the MECP2 gene on the X chromosome, but it’s not usually inherited. Advances in genetics have launched a new era in ...
