Z_3_11 — Genetic Mosaicism and Chimerism
A fundamental assumption of genetics — that every cell in an individual's body carries the same genome — is wrong. Genetic mosaicism (the presence of two or more genetically distinct cell populations within an individual
Z_1_06 — Sex Determination Genetics
Sex determination — the biological process that establishes whether an organism develops as male, female, or an alternative reproductive type — employs remarkably diverse mechanisms across the tree of life. In placental
ZB_2_19 — Epigenetics & Chromatin Modification
Epigenetics — literally "above genetics" — encompasses heritable changes in gene expression that occur without alterations to the DNA sequence itself. The term was coined by Conrad Hal Waddington in 1942 to describe how
L_4_10 — Sex Chromosome Evolution
Sex chromosomes — the genetic elements that determine biological sex in many organisms — represent one of the most remarkable stories in genome evolution. In mammals, the XX/XY system prevails: females have two X chromos
