Answer to Question 1

ANS: C
A polyploid cell is one in which a euploid cell has more than 23 pairs of chromosomes. A diploid cell is when the somatic cell nucleus has 46 chromosomes in 23 pairs. A euploid cell is a cell with multiples of the normal number of chromosomes. A haploid cell has only one member of each chromosome pair, for a total of 23 chromosomes.

Answer to Question 2

ANS: C
The most common cause of Down syndrome is maternal, not paternal, nondisjunction. Transloca-tion is not a cause of this syndrome.
