Multiple Choice

How does selective breeding differ from hybridization in producing desired traits in organisms?

• Selective breeding involves choosing parents with similar traits, while hybridization involves crossing organisms with different traits.

• Selective breeding and hybridization are the same process.

• Hybridization involves choosing parents with similar traits, while selective breeding involves crossing organisms with different traits.

• Selective breeding always produces sterile offspring, while hybridization does not.
