Usage: biology; genetics
2. derived from the same genetic source or ancestor
Usage: biology; genetics

Examples

• Isogenic mice are commonly used in laboratory research because they have uniform genetic backgrounds.
• The two plant strains are isogenic, making them ideal for studying environmental effects on growth.
• Researchers created isogenic cell lines to eliminate genetic variation in their experiments.
• Isogenic organisms allow scientists to isolate and study the effects of single genetic mutations.
• The isogenic population of bacteria ensured that observed differences were due to environmental factors, not genetics.
