Which term is used to describe a record of ancestry in breeding programs?

• A. Meiosis
• B. Pedigree
• C. Conception
• D. Estrus

Answer: (B)

Tracking ancestry in breeding programs is captured in a pedigree, a chart that shows who the parents, grandparents, and earlier ancestors are for each animal. A pedigree records generations, relationships, and genetic connections, which helps breeders understand how traits may be inherited, plan matings to improve desirable traits, and manage inbreeding by seeing how closely related individuals are. The term pedigree emphasizes lineage and family history, which is why it is the correct term for a record of ancestry.

Meiosis is the cell division that halves the chromosome number to form gametes, essential for sexual reproduction but not about recording ancestry. Conception is the moment a new individual is conceived, a process rather than a record. Estrus is the reproductive heat period in female animals, indicating ovulation readiness, not a record of lineage.
