Nondisjunction as a Route to Polyploid Speciation
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
Nondisjunction, per Unit 6's Bio 1187, chromosomes failing to separate during meiosis, produces the unreduced gametes underlying both autopolyploidy and alloploidy.
Show
A gamete with the full diploid number, rather than the normal haploid number, traces to a nondisjunction event during meiosis.
Watch for
Nondisjunction produces polyploid gametes as a byproduct of a meiotic error — polyploidy is not a separate error itself.
