The two members of a homologous pair of chromosomes differ by

Select one:

a. the location of individual genes along each chromosome.

b. the number of genes along the chromosome.

c. the centromere position along each DNA molecule.

d. the precise sequence of DNA in the chromosomes.

e. the length of the p and q arms.

Answer 1

Solution. Option d. The precise sequence of DNA in the chromosomes

The two members of a homologous pair of chromosomes differ by  the precise sequence of DNA in the chromosomes.

Because in homologous chromosomes, one of the pair is inherited from mother and other from father. Homologous chromosomes are pairs of chromosomes with same length, position of centromere, allelic position etc.

Pairs of homologous chromosomes have same location of individual genes, same number of genes along the chromosome, same centromere position and same length of the p and q arms. Therefore, options a, b, c and e are wrong options
