Question

In a species of bird, the migration behavior is determined by two genes. Gene A has two alleles, and Gene B has three alleles. Moreover, the availability of food resources in their habitat affects whether the birds migrate or not. This genetic system is an exception to the two-factor genotype determination because:

Options

The number of alleles for Gene B is more than two.

The environmental factor (food availability) influences the phenotype.

The combination of the genetic and environmental factors makes it more complex.

All of the above.
