For a common trait, prevalence is easily estimated from a random sample of the population. However, this is prohibitively expensive for a rare disease, which is often ascertained through probands [1].

A test cross is a way to explore the genotpye of an organism. Early use of the test cross was as an experimental mating test used to determine what alleles are present in the genotype. An organism's ...

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 ...
