Biology professors and students use tomatoes from campus garden to teach high schools students about genetic diversity. Students learn about dominant and recessive genes and the genetic influence on ...

Epistasis describes how gene interactions can affect phenotypes. Did you know that genes can mask each other's presence or combine to produce an entirely new trait? But what happens when two different ...

The height of pea plants is controlled by a single gene which has two alleles – tall and short. The tall allele is dominant and is shown as T. The short allele is recessive and is shown as t. Complete ...

Your genes code for all your traits. Some genes are dominant and expressed if you receive a copy from one parent. Others are recessive and only apparent if you receive a copy from both parents. Genes ...
