Which selective breeding method involves crossing two individuals with identical or similar sets of alleles?

• A. Hybridization
• B. Inbreeding
• C. Clone
• D. Genome

Answer: (B)

Crossing two individuals with identical or very similar sets of alleles increases the chance that offspring inherit the same versions of many genes, making them genetically very similar. This approach is inbreeding, a breeding method used to keep traits uniform across generations. It raises homozygosity in the offspring, which helps stabilize desirable traits, but can also reveal recessive deleterious alleles if genetic diversity is low. By contrast, hybridization mixes genetically different individuals to combine traits and usually increases heterozygosity. A clone is produced without crossing, yielding an exact genetic copy of a parent. A genome is the complete set of genetic material, not a breeding method.
