Student teams analyze genetic test results for fictional characters, compare their characters' risks of developing specific diseases, and assess the risks for the next generation. Can genetic testing ...

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 ...

Many binary phenotypes do not follow a classical Mendelian inheritance pattern. Interaction between genetic and environmental factors is thought to contribute to the incomplete penetrance phenomena ...

There’s no simple answer, because genetics is complicated and many traits — such as eye colour — are influenced by many genes Why are some genes dominant? Such as those for brown eyes over blue eyes, ...

The purpose of this study is to describe recessive alleles in strictly dominant genes. Identifying recessive mutations in genes for which only dominant disease or risk alleles have been reported can ...
