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 ...

*Laws of Heredity* is an educational film that demonstrates how inheritance operates in statistically predictable ways, presenting the foundational insights first achieved by Gregor Mendel. Through ...

All people have two copies of every gene – one copy inherited from each parent. The NF1 gene mutation is dominant, which means that only one of the two copies of the gene needs to have the mutation to ...

The genotype of an organism is inherited from its parents through the process of reproduction. During sexual reproduction, each parent contributes half of the genetic material to the offspring, ...

Neurofibromatosis type 2 is caused by a change in the NF2 gene located on chromosome 22. This gene encodes a protein known as merlin. Mutations in the NF2 gene disrupt the function of merlin, which is ...

Retinitis pigmentosa (RP) is an eye condition that can be genetic. In this way, people usually need to inherit two copies of a genetic variation that causes RP, one coming from each parent. RP may ...
