What is a common breeding practice for increasing genetic diversity in sheep?

• A. Inbreeding
• B. Line breeding
• C. Crossbreeding
• D. Self-breeding

Answer: (C)

Crossbreeding is a common breeding practice used to increase genetic diversity in sheep. This method involves mating different breeds or strains to produce offspring that benefit from the combined genetic traits of both parent groups. The introduction of new genetic material through crossbreeding can enhance desirable characteristics such as growth rates, wool quality, disease resistance, and overall adaptability to different environments. Using crossbreeding is particularly beneficial when aiming to tackle issues associated with inbreeding, like reduced vigor and increased susceptibility to diseases, as it introduces a broader gene pool. Ultimately, this strategy supports both genetic health and productivity within sheep populations.
