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

Z_1_10 — Chromosome Evolution and Karyotype

Karyotype — the number, size, and morphology of chromosomes in a cell — varies enormously across species, from n=1 in the ant Myrmecia pilosula to n=630 in the fern Ophioglossum reticulatum. Humans have 2n=46 (23 pairs),

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

Z_1_11 — Polyploidy and Genome Duplication

Polyploidy — the possession of more than two complete sets of chromosomes — is a major force in genome evolution, particularly in plants and some animal lineages. Susumu Ohno (1970) proposed that whole genome duplication

Z_1_09 — Copy Number Variation and Structural Genomics

Copy number variations (CNVs) — segments of DNA ranging from ~1 kilobase to several megabases that are present in variable numbers across individuals — represent the most impactful form of genetic variation in the human
