Question

In a particular plant species, the flower petal number is determined by a gene with three alleles, and the position of the flowers on the stem is controlled by another gene with two alleles. This genetic system is an exception to the two-factor genotype determination because:

Options

The number of alleles for the petal number gene is more than two.

There are two different genes involved.

The combined effect of the two genes leads to unpredictable phenotypes.

The inheritance of these genes may not follow Mendelian laws.
