Solution
The correct option is D Both 1 and 2
Alleles are different forms and hence different phenotypic expressions of one gene. For e.g., the gene which codes for the height of pea plant takes two forms: tall and dwarf. An individual contains a pair of alleles and the final phenotypic expression is a result of how both these alleles interact. These alleles segregate during meiosis and each gamete gets only one of the allele.
