a cross of F1 plants heterozygous for height should produce a ratio of tall to short plants of 3:1. Three seeds from such a cross produce three tall plants. what is the probability that a fourth seed will produce a short plant?

each offspring has a 1/4 probability of being short since the ratio is 3:1.

hence the 4th offspring will also have a 1/4 chance of being shrot

3:1, still....i think. i believe that would make it a probability of 25%....
