Question

What is the primary practical application of test crosses in agriculture?

Options

• Eliminating all recessive traits from populations

• Creating mutations in crop varieties

• Plant breeding and crop improvement through genotype identification

• Increasing plant size and yield without genotype knowledge

Answer 1

Test crosses are simple, reliable, and widely used in plant breeding and crop improvement programs. They allow breeders to identify the genotypes of plants with desirable dominant traits, enabling informed selection decisions for future breeding programs.
