Question

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

Answer 1

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”)
