Document Summary

If both are monohybrid -> distribution of progeny will be. 3:1 / 75% : 25% (dominant : recessive) If one is monohybrid and other is recessive -> Distribution of progeny will be 2:2 / 50% : 50% (dominant. If one is monohybrid and other is dominant -> Distribution of progeny will be 4:0 / 100% : 0% (dominant. If both are dihybrid -> distribution of progeny will be 9:3:3:1 / 56. 25% : 18. 75% : 18. 75% : 6. 25% (dominant/dominant : dominant/recessive : recessive/dominant : recessive/recessive) (3:1. [dominant : recessive for one trait] & 3:1 [dominant : recessive for the other trait] {product rule} If one is dihybrid and other is dominant/recessive - If one is dihybrid and other is recessive/dominant - If one is dihybrid and other is dominant/dominant - Xy pair: when both cross -> distribution of progeny is 2:2 /
