Introduction: Chromosomes are long thread-like structures that carry coded genetic information in the form of
Expert Solution & Answer
Answer to Problem 1MC
Correct answer: Option b. “autosomes”
Explanation of Solution
Reason for the correct answer
Option b. is given as “autosomes”
Autosomes, also known as somatic chromosomes, are all the chromosomes present in the body other than the sex chromosomes. For a given species, both male and females have an equal set of chromosomes in all their cells except their gametes; however, different members of the chromosomes may have different structures. These autosomes are essential for influencing all the
Hence, option b is correct.
Reasons for incorrect answers:
Option a. is given as “sex chromosomes”.
Sex chromosomes or allosomes denote the chromosomes that are present in gametes. Male gametes have a different set of chromosomes, while female gametes have a separate set of chromosomes.
Hence, option a. is incorrect.
Option c. is given as “polyploid”.
Polyploid refers to organisms that have more than two sets of chromosomes in the genome.
Hence, option c. is incorrect.
Option d. is given as “chromatids”.
Chromatid includes the duplicated segment of a chromosome.
Hence, option d. is incorrect.
Hence, options a., c., and d are incorrect.
Conclusion
Autosomes are chromosomes that are present in every cell of male and female individuals.
