B Synaptonemal complex occurs during second stage of prophase of first meiotic division called zygotene. During this stage chromosome start paring together any this process of association is called synapsis such paired chromosomes are called homologous chromosomes. The complex formed by a pair of synapsed homologous chromosomes is called a bivalent or a tetrad.

The complex formed by a pair of synapsed homologous chromosomes is called,
1 Univalent
2 Pentavalent
3 Triad
4 Bivalent
Explanation:
D A bivalent is a pair of synapsed homologous chromosomes. It is formed during prophase-I of meiosis. The homologous chromosome are held together by chiasma.

When pollen mother cell of Apple plant undergoes meiotic division, number of chromatids present in Anaphase I, Anaphase II and the number of bivalents respectively are
1 \(34,34,34\)
2 \(34,17,17\)
3 \(34,17,34\)
4 \(17,17,34\)
Explanation:
B The pollen mother cell of an apple plant has 34 chromosomes. In Anaphase-I, the homologous chromosome are separated but the sister chromatids remain attached. So there are still 34 chromatids present, but they are arranged in 17 pairs of bivalents. In Anaphase-II, the sister chromatids of each chromosome separate and move to opposite poles of the cell, so there are 17 chromatids present in Anaphase-II.

In meiosis, crossing over and exchange of genetic material between homologous chromosomes are catalyzed by the enzyme:
1 Phosphorylase
2 Recombinase
3 Transferase
4 Polymerase
Explanation:
B Recombinase is the enzyme that catalyzes crossing over and exchange of genetic material between homologous chromosomes in meiosis.
