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 ...

Crosses in genetics can be presented theoretically in more than one ways. One of the most simple methods of presenting a Cross is using the Punnett Square method. The technique has several advantages, ...

Gregor Mendel's principles of inheritance form the cornerstone of modern genetics. So just what are they? When looking at the figure, notice that for each F 1 plant, the self-fertilization resulted in ...

Genetic crosses involving single genes (monohybrid inheritance) can be shown and examined using Punnett squares. The tall allele is dominant and is shown as T. The small allele is recessive and is ...

Strong Points: Easy to to make crosses and follow generations. Weak Points: Information provided in the app could be more in-depth. Drosophila X is a great resource for students or researchers who are ...
