On the planet Seltaeb, there is a rare recessive condition known as Hofner Bassis (BB) in the Blue Meanies, a race whose genomes are identical to that of humans. Individuals with this condition can be clearly identified, as they are very musically gifted. The two alleles at this locus are B (the trait allele) and b. If both parents are known to be carriers for the recessive gene, what is the probability that they will have an affected child

the law of original horizontality explains:   why rocks appear in layers. correct answer: b the law suggests that all rock layers are originally laid down (deposited) horizontally and can later be deformed.   the principle is used by geologists to make assumptions about the relative ages of sedimentary rocks.

mass and weight are closely related because mass affects the weight of an object experiencing the effects of gravity. weight is the measure of the force of gravity on an objects's mass, while mass is the measure of how much matter there is in an object.
