Explanation:
The case shown in the question above explores simple Mendelian traits, since it shows a population where individuals of the same species present the dominant allele (R- red) and the recessive allele (r- white). We can project, then, that this population has an allele balance, where it is possible to find 20 red beans, which have the dominant allele and 20 white beans, which present the recessive allele.
