Human Trait Technologies Practice Test

A plant company uses tissue culture (cloning) to make many identical banana plants from one parent plant that produces very sweet fruit. The cloned plants grow and produce fruit with similar sweetness, but when the company later grows banana plants from seeds, sweetness varies widely. Humans can influence trait inheritance using technology. Which statement about the technology is supported by the evidence?

In a classroom model, colored beads represent alleles for flower color in a plant population. Each “generation,” a student (acting as a farmer) removes plants with white flowers from the breeding group and allows only purple-flowered plants to produce seeds. After several model generations, purple becomes much more common. Which statement best links the model technology to real inheritance?
