The failure of sister chromatids to separate during meiosis is calledsynapsis. crossing-over. tetrad formation. disjunction. nondisjunction.

Non disjunction is the answer.

Synapsid is the chromosome coming close to each other to cross over.

Crossing over is the process of interchanging parts at a particular allele (loci)

Tetrad is a formation of chromosomes (looks like this “XX”)

correct answer: understand the different control methods available
