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.

On a recent expedition to a remote region of northern canada, scientists uncovered skeletal remains from about 100,000 years ago. surprisingly, all the skeletal remains, which included many species from differing biological families and spanned about two thousand years, showed evidence of experiencing temperatures in excess of 1000 degrees fahrenheit (or 538 degrees celsius). which of the following, if true, best explains the apparent paradox between the cold environment and the evidence of the bones experiencing hot temperatures? (a) chemical changes that naturally occur during the process of decay in only one north canadian species produce the same evidence of the species' skeletons being exposed to hot temperatures as the expedition scientists found. (b) a little over 103,000 years ago, a large fire is known to have occurred in northern canada. (c) strong evidence exists that as early as 70,000 years ago, homo sapiens around the world relied heavily on fire to cook animals. (d) in the same expedition and in roughly the same layer of excavation, scientists found rudimentary wood cutting and hunting tools used by early humans.
