Explanation:
Detailed explanation-1: -The tight pairing of the homologous chromosomes is called synapsis. In synapsis, the genes on the chromatids of the homologous chromosomes are aligned with each other.
Detailed explanation-2: -During MI, homologous chromosomes pair and are held together by synapses. Chiasmata form along the chromosomes at positions where genetic exchange or recombination takes place. These physical connections are important for keeping chromosomes together until they separate in anaphase I.
Detailed explanation-3: -Definition. Two chromosomes in a pair – normally one inherited from the mother and one from the father. For example, the two copies of Chromosome 1 in a cell would be referred to as homologous chromosomes.
