The segregation of alleles occurs during the process of _____ in eukaryotic organisms.
Correct answer: C. Meiosis
- A. Mitosis
- B. Binary fission
- C. Meiosis
- D. DNA replication before cell division
Explanation
Alleles of a gene separate during meiosis, when homologous chromosomes are pulled apart in anaphase I, which is the physical basis of Mendel's law of segregation. Mitosis and binary fission produce identical cells without separating alleles, and DNA replication only copies them.

About Mendel's Laws of Inheritance
Mendelian inheritance explains how alleles separate into gametes and assort during reproduction, producing predictable genotype and phenotype ratios. Questions cover dominance, recessiveness, homozygous and heterozygous conditions, the laws of segregation and independent assortment, monohybrid and dihybrid crosses, test crosses and the limits caused by linked genes.
