Starch synthesis in pea is an example of incomplete dominance. When the dominant allele is not completely able to mask the expression of a recessive allele it is called incomplete dominanace. The gene for starch synthesis in pea seeds has two alleles B and b. In BB genotype, large starch grains are produced. After maturation the seeds are round. In bb homozygous condition, smaller starch grains are produced and mature seeds are wrinkled. Bb heterozygous form round seeds so that B seems to be dominant allele. However, Bb seeds have starch grains of intermediate size, showing incomplete dominance.

Given below are two statements: Statement I: Failure of segregation of chromatids during cell cycle resulting in the gain or loss of whole set of chromosome in an organism is known as aneuploidy. Statement II: Failure of cytokinesis after anaphase stage of cell division results in the gain or loss of a chromosome is called polyploidy. In the light of the above statements, choose the correct answer from the options given below:
