Barr bodies and drumsticks are of what signifcance to genetists and biolgistsa. They indicate the presence of abnormal sex cells b. The inidicate the presence of more than one X chromosome in the cells c. The indicate male calls d. They signify the presence of sex linked traits

Sure, here are the step-by-step solutions: 1. Females have two X chromosomes, while males have one X and one Y chromosome. 2. In female cells, one of the X chromosomes is randomly inactivated during embryonic development. 3. The inactivated X chromosome becomes condensed and forms a structure called a Barr body. 4. The Barr body can be visualized under a microscope as a dark, compact mass within the nucleus of the cell. 5. In addition to the Barr body, female cells may also contain a structure called a drumstick, which is a small, elongated body that is attached to one of the Barr bodies. 6. The drumstick is thought to be formed from the tip of the inactivated X chromosome, which protrudes from the Barr body. 7. Together, the Barr body and drumstick are characteristic features of female cells and can be used to distinguish them from male cells.
