chromosomal crossover









































chromosomal crossover (or crossing over) is the exchange of genetic material between two homologous chromosomes non-sister chromatids that results in recombinant chromosomes during sexual reproduction. it is one of the final phases of genetic recombination, which occurs in the "pachytene" stage of prophase i of meiosis during a process called synapsis. synapsis begins before the synaptonemal complex develops and is not completed until near the end of prophase i. crossover usually occurs when matching regions on matching chromosomes break and then reconnect to the other chromosome.

while these sentences are actually grammatical, the reading indicated by the subscripts is robustly unavailable. for instance, the first sentence (sentence a) cannot be interpreted to mean that susan told them to vote for herself (i.e. susan).









































section::::strong and weak crossover.:weak crossover.









































crossover is "weak" when the coreferential reading is marginal, that is, when the coreferential reading is not clearly unacceptable, but rather just quite unlikely. typical cases of weak crossover occur when the expression that has been "crossed over" is a possessor inside a noun phrase, e.g.
