genetic drift is caused by gene splicing by the crossing over during meiosis 1 and/or 2. this can cause many disorders and inherited diseases that could stay in your blood line for a long time. It also can benefit however by giving possibly giving a stronger inheritance that benefits survival. this all relates to evolution because it shows how species and also offspring differ. the stronger the genes, the more likely you are to survive.
Answer:
A tetrad is a four part structure formed during the prophase I of meiosis I which is formed by the homologous chromosomes which is composed of two identical chromatids.
The tetrad formation takes place when a proteinaceous meiosis-specific nuclear structures called synaptonemal complex is formed between two homologous chromosomes which mediates the tight associations of the homologous chromosomes.
The synaptonemal complex consists of two ladder like lateral elements which attaches the chromatin of the homologius chromosomes. The central region of the synaptonemal complex is composed of the transverse filaments and the central element which bridge the space between the the lateral elements.
This attachment of the chromatin to the synaptonemal complex mediates the chromosome pairing and form tetrad.
