Select the two terms that correctly complete this statement. Observable traits exhibited by an organism do not always indicate the exact genetic makeup of
that organism because of recessive alleles and <span>polygenic traits</span>. 
        
                    
             
        
        
        
D. Species with an odd number of chromosome sets (triploid and pentaploid) would be infertile.  
E. Aneuploid individuals (monosomic and trisomic) would have reduced fertility.
Explanation - Chromosomes generally happens to occur in the set of two. Organism that have more than two sets of chromosome are called polyploids. Polyploids that have odd or uneven count of sets of chromosome are sterile or fully infertile. 
Example - triploid (3n), pentaploid (5n) because their gametes and offsprings are aneuploid. Aneuploidy is addition of entire chromosome to the already existing normal set of chromosome. Aneuploids are unable to produce viable offspring because their fertility got decreased as the zygote formed after the fertilization itself is aneuploid.

Answer:The answer is c
Explanation: The mean is usually a good choice to represent a whole data set as a single number.
Mean is derived by adding a whole data and dividing the data by the number of points. It can also be referred to as the average that is used to derive the central tendency of data. It also measures the central tendency in a data set. It can be called an average.
