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 ...

The inheritance of fur colour in mice is controlled by a single gene. White fur is recessive. Grey fur is dominant. Two mice that are heterozygous for the fur colour gene mate. Determine the ...

Discover the fascinating world of Mendelian genetics, where the inheritance of traits from parents to offspring follows predictable patterns. This concept explains how genetic information is ...

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 ...

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 ...

Genes come in different varieties, called alleles. Somatic cells contain two alleles for every gene, with one allele provided by each parent of an organism. Often, it is impossible to determine which ...

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 ...

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.
