PLOIDY "is the number of sets of chromosomes found in a cell." https://genetics-notes.wikispaces.com/Ploidy View in LinkedIn

DIPLOID AND HAPLOID. "Diploid (2n) describes a cell that contain two copies of each chromosome. Nearly all the cells in the human body carry two homologous, or similar, copies of each chromosome. The only exception is cells in the germ line, which go on to produce gametes, or egg and sperm cells. Germ line cells are haploid (n), which means they contain a single set of chromosomes. In diploid cells, one set of chromosomes is inherited from the individual's mother, while the second is inherited from the father. Humans have 46 chromosomes in each diploid cell." https://lnkd.in/dMr2dWf View in LinkedIn

HALVING CHROMOSOMES. "Sexually reproducing organisms rely on the precise reduction of chromosome number during a specialized cell division called meiosis. Whereas mitosis produces diploid daughter cells from diploid cells, meiosis generates haploid gametes from diploid precursors." An outstanding review of meiosis. https://lnkd.in/dd-eUTZ View in LinkedIn

GENETIC REFRESHING. "Meiosis is the cell division that reshuffles genetic information between generations." https://lnkd.in/dE-FQEZ View in LinkedIn

GONADAL MEIOSIS. "Once in the gonad, germ cells acquire sex-specific morphologies and the ability to undergo meiosis to generate egg and sperm." http://www.sciencedirect.com/science/article/pii/S009286740800202X View in LinkedIn

SEXUAL SELECTION THEORY "developed from Darwin’s original intuition, is a cornerstone of evolutionary theory and represents the most parsimonious and robust explanation for a bewildering array of evolutionary patterns and diversity." https://lnkd.in/dbDjBx2 View in LinkedIn

DIAGNOSTIC. "A major source of signs of sex for any species is its genome." https://lnkd.in/deZ8DED View in LinkedIn

QUANDARY. "The pervasiveness of sex, given its varied and potentially large costs, is highly perplexing." https://lnkd.in/ePUmiA8 View in LinkedIn

EUK AND ASEXUALITY. "Whereas absence of sex is considered as something scandalous for a zoologist, scientists studying protists, which represent the majority of extant eukaryotic diversity, are much more ready to accept that a particular eukaryotic group has not shown any evidence of sexual processes." https://lnkd.in/deZ8DED View in LinkedIn
