Key takeaways: 1. cross breeding produces inferior offspring
2. Using dna barcodes and environmental dna is a great way to know about a specific area’s ecosystem’s health, though it lacks further informations about the particular species, like population size.

Thank you so much for the video! It really helped me understanding the concept better. However, are you planning or releasing A4.1? As well as the exam practice? It’ll be really helpful for my exam.

You are welcome! In time everything will be created. I can't give exact dates as the process is long, but I am hoping to have most (if not all) of the 2025 exam content out before the first exam in May.
