Monohybrid cross ek genetic experiment hai jisme ek hi trait ke liye heterozygous parents cross kiye jaate hain, jisse F2 generation mein 3:1 ka phenotypic ratio milta hai. Ye ratio dominant aur recessive alleles ke segregation se aata hai, jaise Mendel ne pea plants mein dikhaya. Lekin mujhe yaad aata hai mere coaching ke notes, jahan sir ne bataya tha ki ye 'ideal' ratio hai, par real life mein kabhi-kabhi incomplete dominance ya linkage se alag hasil hota hai. Maine apni practical file mein tomato plants ke results likhe the, jahan ratio thoda alag aaya tha — isliye mujhe laga ki kitabon wala 3:1 bas starting point hai, asli duniya thodi complicated hoti hai.
