Question

In a human karyotype, chromosomes are arranged in 23 pairs. If we choose one of these pairs, such as pair 14, which of the following do the two chromosomes of the pair have in common?
A) Length and position of the centromere only.
B) Length, centromere position, and staining pattern only.
C) Length, centromere position, staining pattern, and traits coded for by their genes.
D) Length, centromere position, staining pattern, and DNA sequences.
E) They have nothing in common except they are X-shaped.

Answer 1

Answer: Option C

Explanation:

The human karyotype consists of 23 pairs of chromosomes. If a single pair of chromosome is picket out of the whole karyotype then the chromosome pair will have the some similarities or will have in common some traits.

The length of the chromosome, centromere position, traits and staining pattern will be same for this pair of chromosome.

Hence, the correct answer is Option C
