Which breeding method utilizes a superior female to enhance genetics of a herd?

• A. Embryo transfer
• B. Artificial insemination
• C. In vitro fertilization
• D. Selective breeding

Answer: (A)

Embryo transfer focuses on multiplying the impact of a superior female’s genetics. By super-ovulating a high-quality dam, collecting multiple embryos, and transferring them into recipient females, you get many offspring that carry her desirable traits. This dramatically increases the dam’s genetic contribution to the herd in a single generation, speeding genetic improvement. In contrast, artificial insemination spreads genes from top males, not the dam’s own genetic potential; in vitro fertilization is a lab-based fertilization method that doesn’t inherently maximize one female’s progeny number, and selective breeding is a broad term for choosing mates rather than the specific technique of expanding a superior dam’s influence.
