The correct answer is as follows.
This is because my parents were heterozygous for the color of the beans. The color of the plant beans is the case of simple Mendelian laws, as there are only two choices for the color of the beans.
What is the meaning of Mendel's laws?Mendel's laws refer to a specific pattern of how a trait is passed from parent to offspring. These common patterns were established by the Austrian monk Gregor Mendel, who conducted thousands of experiments on bean plants in the 19th century.
What is an example of a heterozygous?If the two versions are different, the genotype of the gene is heterozygous. For example, a heterozygous hair color means that there is one red hair allele and one brown hair allele. The relationship between the two alleles affects which trait is expressed.

What is species competition?Competition is an ecological relationship that occurs between organisms of the same or different species. We say that competition is intraspecific when individuals of the same species are involved, and that it is interspecific when dealing with different species.
Interspecific competition is an interaction between two species that causes damage to one or both of them. In general, competition can be for resources such as: space, food or nutrients, light, organic waste, among others.
