The correct response is:
Yes, the probability of any outcome is independent of prior outcomes.
This is because genetic probability applies independently to each individual offspring. Although there is a calculated 50% chance for the offspring to inherit the trait for short hair and a 50% chance for long hair, this does not guarantee that a certain number or proportion of offspring will show those traits in a small sample size. It is entirely possible, albeit unlikely, for all 11 offspring to exhibit the long hair trait given the specified genetic makeup of the parents (one heterozygous for short hair and one homozygous for long hair). The outcomes of offspring are determined by chance, and in random distribution, it is feasible to observe all offspring exhibiting one trait.
