Detailed explanation-1: -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.
Detailed explanation-2: -What are Homologous Chromosomes? Homologous Chromosomes are made of chromosomal pairs of the same length and centromere positions for the genes corresponding to the same loci. Typically one of the chromosomes is inherited from the father and the other from the mother.
Detailed explanation-3: -The pairs of autosomes are called “homologous chromosomes.” Homologous chromosomes have all of the same genes arranged in the same order, but there are small differences in the DNA letters of the genes.
Detailed explanation-4: -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-5: -For example, the 46 chromosomes in a human cell can be organized into 23 pairs. These paired chromosomes are called homologous chromosomes.
