Bivalent is half the number of chromosomes

WebThe diploid cell with chromosomes 4 contains 2 pairs of homologous (maternal and paternal) chromosomes. These DNA replicates and there is an increase in the number of chromatids which are known as bivalents with two sister chromatids in each chromosome.
