This involves the pairing, or synapsis, of homologous chromosomes in which the chromosome from the mother pairs with the analogous chromosome from the father.

Dernburg studies the first steps in meiosis; steps that, in humans, are completed in the ovaries of a female well before she is born. This involves the pairing, or synapsis, of homologous ...

During meiosis, homologous chromosomes pair to form bivalents, enabling crossing-over—the physical exchange of chromatid segments. This crucial step requires proper alignment and synapsis of ...

Researchers Find Key Gene In Production Of Egg And Sperm Date: January 5, 2004 Source: University Of California - Berkeley Summary: How the chromosomes in germ cells pair off, trade a few genes ...

After pairing, zipping (called synapsis) and recombination, the chromosome pairs are pulled apart, then the duplicated chromosomes are separated, and the cell splits into four gametes, each with ...

But, because pachytene is the stage at which homologous pairs become fully synapsed, the authors suggest that Spo11 could also have a structural function in stabilizing synapsis.
