Answer:

Almost 99% of <u>the mass of the human body is made up of six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. </u>Only about 0.85% is composed of another five elements: potassium, sulfur, sodium, chlorine, and magnesium.

Exactly 989527/1048576, or approximately 94.37%  
Since each trait is carried on a different chromosome, the two traits are independent of each other. Since both parents are heterozygous for the trait, each parent can contribute 1 of a possible 4 combinations of the alleles. So there are 16 possible offspring. I'll use "a", "A", "b", "B" to represent each allele and the possible children are aabb, aabB, aaBb, aaBB, aAbb, aAbB, aABb, aABB, Aabb, AabB, AaBb, AaBB, AAbb, AAbB, AABb, and AABB 
Of the above 16 possibilities, there are 7 that are homozygous in an undesired traint and 9 that don't exhibit the undesired trait. So let's first calculate the probability of "what are the chances that all 5 children not exhibiting an undesired trait?" and then subtract that result from 1. So 
1-(9/16)^5 = 1 - 59049/1048576 = 989527/1048576 which is approximately 0.943686485 = 94.3686485%  
So the answer is exactly 989527/1048576, or approximately 94.37%

Is there a picture with this question? It seems like there's background information which isn't being shown here.

Pedigrees are basically a map of alleles for family trees
 
                   ______Person1 -- Person2_____
                  I                I                  I                 I
        __Person3_   Person 4     Person5    _Person6___
       I                   I                          I            I                    I
   Person7 Person8                 Person9   Person10  Person11

And under everyone's name you write their alleles.

Punnett squares give the probability of someone having genes based on their parents' genes.
 
                             Parent1 (Aa)                   or                      Parent1 (aa)
