The correct sequence of gamete formation by an F1 plant (RrYy) during meiosis, leading to the principle of independent assortment, is:
I. Alignment of chromosome pairs at the metaphase plate independently.
II. Separation of homologous chromosomes during anaphase I.
III. Formation of four haploid gametes with genotypes RY, Ry, rY, ry.
IV. Segregation of alleles for each gene (R/r and Y/y) into different gametes.
V. Pairing of homologous chromosomes to form bivalents.
Choose the correct answer from the options given below:
- I → V → II → IV → III
- V → II → I → IV → III
- V → I → II → IV → III
- II → V → I → III → IV
Answer
(C) V → I → II → IV → III
