Answer:

Probability is a method for determining the likelihood of something uncertain occurring. If you flip a coin, you do not know whether it will be heads or tails, but probability can tell you that there is a 1/2 chance of either happening. Probability is a method used to predict the likelihoods of uncertain outcomes. It is important for the field of genetics because it is used to reveal traits that are hidden in the genome by dominant alleles. Probability allows scientists and doctors to calculate the chance that offspring will inherit certain traits, including some genetic diseases like cystic fibrosis and Huntington's disease.
