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 ...

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 ...

This module can be used by students to practice working with Punnett Squares, and in doing so reinforce their understanding of genetic variation as a result of sexual reproduction. The presentation ...

Determine the parental genotypes - the allele combinations for the male and female. You can use any letter you like but select one that has a clearly different lower case, for example: Aa, Bb, Dd.

After tracking physical characteristics of the common pea plant through multiple generations, Gregor Mendel realized that inheritance follows specific patterns. Mendel’s discovery led to what we now ...

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 ...

Jenny writes: “I’m nearing the end of getting my undergrad in Zoology and I decided to do something to commemorate it. I like the simplicity of a Punnett square and I like that such complicated ...
