How could genetic engineering be used to produce a more successful crop in a hot,
dry climate?
Non-essential DNA could be removed from the genomes of the crop plants.
ODNA from plants adapted to dry areas could be added to the genomes of the
crop plants.
RNA from a variety of nonagricultural plants could be added to the genomes of
the crop plants.
OmRNA transcripts of genes from dry weather crops could be added to the
fertilizer used on the crop plants.

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
