A bivalent consists of:
Updated On: Apr 28, 2025
- two chromatids and one centromere
- two chromatids and two centromeres
- four chromatids and two centromeres
- four chromatids and four centromeres.
Hide Solution
Verified By Collegedunia
The Correct Option is C
Approach Solution - 1
A bivalent consist of four chromatids and two centromeres. Bivalent is a pair of homologous chromosome lying together in the zygotene stage of prophase I of first meiotic division.
So, the correct option is (C): four chromatids and two centromeres.

Approach Solution -2
A bivalent denotes a pair of two homologous chromosomes. Although each chromosome consists of two chromatids, there are a total of four chromatids and two centromeres, with each centromere positioned at the center.
So, the correct option is (C): four chromatids and two centromeres.

Cell: The Unit of Life
- A cell is derived as the functional and structural unit of life. Every cell is surrounded by a cell membrane that dissects the external and internal environments of the cell. The interior environment of a cell is called the cytoplasm.
- It carries cellular machinery and structural elements. The nucleus is present in the center of the cell, which includes all the hereditary information of an organism. Some of the molecules present in the cell are protein, carbohydrates, starch, and sugar.
