Question

Which term describes the rearrangement of genes that causes an organism's genes to differ from those of it's parents?

Answer 1

Synapsis:  

•Early during the first nuclear division. •Homologous chromosomes pair along their length. •Held tightly by protein ‘zipper’.

Homologous Recombination: 

•Genetic exchange (crossing over) occurs between homologous chromosomes. It then becomes a mix of both paternal and maternal genes (father and mother respectively)
