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.

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 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 ...

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 ...

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 ...

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 ...
