The little four-square grid we drew in school while learning about genetic crossing has a name: the Punnett Square. These squares are a way to predict the possible genetic outcomes of the offspring ...

Between heat and showers, my garden is looking rather healthy if a bit overgrown. Aside from the raspberries, the produce I most look forward to are peas. Sweet peas are already in bloom, providing a ...

Through a combination of observation and mathematical estimation, scientists can evaluate the amount of genetic variation in different populations. Upon doing so, they can then analyze differences in ...

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 small allele is recessive and is shown as t. Complete ...

Colleen Laurich recently was a junior high science teacher and is now a first-grade teacher. Cathy Neiheisel is technology director and a computer teacher at Divine Infant Jesus School in Westchester, ...

Our genes are inherited from our parents, and the different combinations of these genes make us unique. Genetic inheritance controls the characteristics of all living things. This short video explains ...
