The correct Answer is:
**Step-by-Step Solution:** (i) To fill in the first blank, we need to understand the concept of segregation of alleles. According to Mendel's laws of inheritance, specifically the law of segregation, alleles segregate randomly during the formation of gametes. Therefore, the correct term to fill in the blank is "random." So, the completed sentence is: "Segregation of alleles is a **random** process." (ii) For the second blank, we need to identify the condition under which the dwarf character appears. In genetics, the dwarf trait is typically represented by a recessive allele (e.g., "t"). The dwarf character will only manifest when an individual has two copies of the recessive allele (homozygous condition), which means both alleles are the same (tt). Thus, the completed sentence is: "Dwarf character shows itself in **homozygous** condition." **Final Answers:** (i) Segregation of alleles is a **random** process. (ii) Dwarf character shows itself in **homozygous** condition. ---
