This explains the predicted ratio or chances of having a particular trait or character in a cross or transmission from generation to another. This explains the predicted ratio of 3:1 for monohybrid cross and 9:3:3:1 for dihybrid cross.
Probability is usually expressed in units ranging from 0-1. Two principles are necessary is understand the importance or probability in genetics.
- The result of one
trial of a chanced event does not affect the result of latter traits of the event
- The chance that two independent events will occur together simultaneously is the product of their chances of occurring separate question
In a plant of genotype Tt, what is the probability that a gamete will contain gene t?
