If an allele is found at a frequency of 0.8 in a population that is in Hardy- Weinberg equilibrium, and an individual is heterozygous for that allele, what is the probability they will pass on that allele to their offspring?
A) 0.2
B) 0.64
C) 0.8
D) 0.5

In Hardy-Weinberg equilibrium, the allele frequency remains constant from generation to generation, which means the probability of passing on that allele is simply the frequency of the allele in the population. Therefore, the probability of passing on the allele for a heterozygous individual is 0.5.
