Question

Statement 1: Every individual organism contains two or more alleles for each trait.
Statement 2: Alleles segregate (separate) during meiosis such that each gamete gets only one of the alleles.

Which of the given statements is correct?

• A. Only 2
• B. Only 1
• C. Neither 1 nor 2
• D. Both 1 and 2

Answer 1

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.
