Joined sister chromatids of each pair of homologous chromosomes come into side-by-side contact or ____ to form a tetrad.

Question

Quizplus · Accepted Answer

When sister chromatids of each pair of homologous chromosomes come into side-by-side contact, they form a structure known as a tetrad through a process known as synapsis. Crossing-over occurs during synapsis, resulting in the exchange of genetic material between homologous chromosomes, leading to genetic diversity. Locus refers to the specific location of a gene on a chromosome, and dyad refers to a chromosome or chromosomal structure composed of two chromatids. Therefore, the correct answer is D, synapse.
