Chapter 10, Problem 1MC

Pairs of chromosomes with almost identical genetic composition and that are found in cells of both males and females are called

a. sex chromosomes.

b. autosomes.

c. polyploid.

d. chromatids.

Expert Solution & Answer

Summary Introduction

Introduction:

There are 23 pairs of chromosomes in each human cell. These chromosomes carry genetic information, like a blueprint. This information helps the cells to perform their tasks and passes the genes to the future generation.

Answer to Problem 1MC

Correct answer:

Pairs of chromosomes with almost identical genetic compositions, which are found in the cells of both males and females, are called autosomes.

Explanation of Solution

Explanation/justification for the correct answer:

Option (b) is given that pairs of chromosomes with almost identical genetic composition and that are found in the cells of both males and females are called autosomes. Autosomes are found in the diploid cells of both sexes and contain almost identical deoxyribonucleic acid (DNA) sequences. There are 22 pairs of autosomes in each cell. Hence, option (b) is correct.

Explanation for the incorrect answers:

Option (a) is given that pairs of chromosomes with almost identical genetic composition and that are found in the cells of both males and females are called sex chromosomes. Sex chromosomes are two in number in each cell. In females, the sex chromosomes are XX while in males the sex chromosomes are XY. So the sex chromosomes are different in different sexes. So, it is an incorrect option.

Option (c) is given that the pairs of chromosomes with almost identical genetic composition and that are found in the cells of both males and females are called polyploid. A polyploid is a cell with three or more copies of each homologous chromosome. So, it is an incorrect option.

Option (d) is given that cell walls of the pairs of chromosomes with almost identical genetic composition and that are found in the cells of both males and females are called chromatids. Chromatids are each one of the two thread-like strands or copies made before mitosis and meiosis. They are not present in the cell rest of the time. So, it is an incorrect option.

Hence, options (a), (c), and (d) are incorrect.

Conclusion

Therefore, pairs of chromosomes with almost identical genetic composition and that are found in the cells of both males and females are called autosomes. The sex chromosomes are different in the different sexes.
