can help me writing a summary please Chromosomal Aberrations and Human Disorders In addition to mutations that alter the information content of a single gene, chromosomes may be subjected to more extensive alterations that occur most commonly during cell division. Pieces of a chromosome may be lost or segments may be exchanged between different chromosomes. Because these chromosomal aberrations follow chromosomal breakage, their incidence is increased by exposure to agents that damage DNA, such as viral infection, X‐rays, or reactive...

Unit 3 Study Resource Meiosis • Process by which diploid cells create haploid cells NOT part of the cell cycle > only some cells ever undergo meiosis During meiosis I, homologous chromosomes line up to allow them to be separated into two new cells o They can become "tangled" during this phase, which leads to crossing-over (rearranging the alleles) O Result of meiosis I is two non-identical haploid cells Meiosis Il looks very similar to mitosis, in that sister chromatids...
