Question
OB01-Kenobi-ism in Jedis is controlled by a recessive gene (a). The other allele at the locus is A (Wild-type). Being homozygous for the a allele (genotype = aa) increases the force in a Jedi, whereas individuals who have one of the other two genotypes (Aa or AA) have standard level force values. From mating between two non-OB01 carriers (both have Aa genotypes), five children are born and raised. What is the probability that: at least one of the children has genotype aa? Hint: list the probabilities of the possible genotype frequencies among the offspring.
