Synapsis

Science / Biology / Synapsis: The alignment of chromosomes during meiosis I so that each chromosome is beside its homologue.

Tetrad

Science / Biology / Tetrad: The four chromatids in each cluster during synapsis; formed by the two sister chromatids in each of the two homologous chromosomes. MORE

Assortment

Science / Biology / Assortment: A way in which meiosis produces new combinations of genetic information. Paternal and maternal chromosomes line up randomly during synapsis, so each daughter cell is likely to receive an assortment of MORE

Recombination

Science / Biology / Recombination: A way in which meiosis produces new combinations of genetic information. During synapsis, chromatids may exchange parts with other chromatids, leading to a physical exchange of chromosome parts; thus, MORE
