ব্যাক ক্রস মানে F1 এ যে অপত্য (Tt)উৎপন্ন হবে তার সাথে জনিতৃ জনুর(TT/tt) কোনো জীবের সংকরায়ন ঘটানো....তাহলে ধরো তুমি F1 এ উৎপন্ন অপত্য Tt এর সাথে TT এর সংকরায়ন ঘটালে তাহলে চেকার বোর্ডের সাহায্যে তুমি দেখতে পাবে বিশুদ্ধ লম্বা এবং সংকর লম্বা এর মধ্যে অনুপাত টা 1:1 ই হবে.... তুমি বলছো ফিনোটাইপ 100% অর্থাৎ সবাই লম্বা তাই বলতে চেয়েছো হয়তো.. কিন্তু তার মধ্যে বিশুদ্ধ লম্বা আর সংকর লম্বা অনুপাত টা একবার ভালো করে দেখে নিও কেমন....যদি এখনো কোনো confusion থাকে অবশ্যই জানিও....
