Allopolyploids are common in natural ecosystems (Grant, 1981). They arise as a result of distant hybridization (and chromosome doubling) between related species containing different sets of related, ...

Due to the presence of allelic drop-out when assaying single cells in PGD, markers along a very long stretch of DNA can indicate whether the chromosome carries a translocation in an embryo. This ...
