A certain type of flower has two alleles for color (blue, purple), and two alleles for stem height (tall, short). A tall blue flower and a short purple flower are crossed resulting in tall blue flowers , short blue flowers , tall purple flowers , and short purple flowers . What law does this example demonstrate

Mendel’s law of independent assortment states that during meiosis, genes do not influence each other with regard to the sorting of alleles. This means that every possible combination of alleles for every gene is equally likely to happen, so traits have an equal opportunity of occurring together. This means, when two or more characteristics are inherited, those characteristics assort independently during gamete production. The law is only true for traits that are not linked (in this example, flower color and stem height).

In other words: the inheritance of one trait will not affect the inheritance of another. The calculation of any genotype combination is the probability of the desired genotype at the first locus multiplied by the probability of the desired genotype at the other loci.
