Chemical modifications to DNA or histones that affect gene activity without changing the actual DNA sequence.
Having extra complete sets of chromosomes (common in plants).
Each individual has two alleles for a trait, which separate during gamete formation so that each gamete carries only one allele. Principles of Genetics and Cytogenetics
The semi-conservative process of copying the genome.
Genetic principles and cytogenetics provide the framework for understanding how life encodes, replicates, and expresses its instructions. 1. Mendelian Principles (Classical Genetics) Chemical modifications to DNA or histones that affect
Cytogenetics identifies abnormalities that lead to genetic disorders:
Genes located close together on the same chromosome tend to be inherited together, defying independent assortment. the physical carriers of genetic material.
Cytogenetics bridges the gap between cell biology and genetics by studying , the physical carriers of genetic material.
