Split the alleles for each parental type and add them into your Punnett square around the edges. Work out the new possible genetic combinations inside the Punnett square. Use this to answer the ...

Mendel's principles can be used to understand how genes and their alleles are passed down from one generation to the next. When visualized with a Punnett square, these principles can predict the ...

Pearson's chi-square test works well with genetic data as long as there are enough expected values in each group. In the case of small samples (less than 10 in any category) that have 1 degree of ...

Medically reviewed by Andrew Greenberg, MD Eye color genetics is complex, with multiple genes from each parent determining a ...

Grey fur is dominant. Two mice that are heterozygous for the fur colour gene mate. Determine the probability that the offspring will have grey fur. In this Punnett square the top row shows the ...
