The semi-conservative process of copying the genome.

Chemical modifications to DNA or histones that affect gene activity without changing the actual DNA sequence. Principles of Genetics and Cytogenetics

A two-step division reducing the chromosome number by half to produce haploid gametes, introducing genetic variation via crossing over . 3. Chromosomal Variations The semi-conservative process of copying the genome

Cytogenetics bridges the gap between cell biology and genetics by studying , the physical carriers of genetic material. Principles of Genetics and Cytogenetics

Each individual has two alleles for a trait, which separate during gamete formation so that each gamete carries only one allele.
