Question
Assertion: The complex formed by a pair of synapsed homologous chromosome is called as tetrad. Reason: Each of the homologous chromosomes in meiotic prophase I consists a two closcly apposed sister chromatids.
Step 1
Each chromosome in this pair is made up of two sister chromatids. These sister chromatids are identical copies of each other and are held together at the centromere. Show more…

Assertion: The complex formed by a pair of synapsed homologous chromosome is called a bivalent or a tetrad. Reason: The first two stages of prophase I are relatively short lived when compared to the next stage that is pachytene.
A tetrad is composed of two chromosomes with two sister chromatids each. four sister chromatids attached at a common centromere. two sister chromatids with separate centromeres. four sister chromatids with a common centromere.
A tetrad consists of two homologous chromosomes, each consisting of a single DNA strand. It also includes one duplicated chromosome, which consists of two sister chromatids. Additionally, there is one duplicated chromosome consisting of two nonsister chromatids, two homologous chromosomes each comprised of two nonsister chromatids, and two homologous chromosomes each comprised of two sister chromatids. During metaphase, the homologous chromosomes align at the spindle equator, with each homologue facing both spindle poles. They can also face opposite spindle poles or not face either spindle pole.
