What is the purpose of gene “knockout” experiments? It can be used to determine how specific biological processes are impacted if a gene is defective or mutated.

It can help scientists determine how an organism will be affected if a gene is defective or mutated.

It can be used to determine how a specific drug affects gene function.

All of the above are purposes of gene “knockout” experiments.

The diagram shows the results when two parents are crossed. the letters represent alleles for a trait that is controlled by three different genes. which best describes this inheritance pattern? multiple allele because a trait is controlled by three different genes polygenic because the offspring have alleles from both parents multiple allele because the offspring have alleles from both parents polygenic because a trait is controlled by three different genes
