Which condition or statement exemplifies the concept of genomics rather than genetics?

A. The gene for insulin is located on chromosome 11 in all people.

B. Expression of any single gene is dependent on inheriting two alleles.

C. Sex-linked recessive disorders affect males more often than females.

D. One allele for each gene is inherited from the mother and one is inherited from the father.

A. The gene for insulin is located on chromosome 11 in all people.

Explanation:

Genomics includes the study of the content, organization, function and evolution of genetic information in a complete genome. The genomic term is relatively recent. It is considered that it was coined by Thomas Roderick, in 1986, to refer to the subdiscipline of genetics dedicated to the study of cartography, sequencing and analysis of the functions of complete genomes.

Insulin is formed as pre-proinsulin of the precursor protein. This is encoded by a 14kb series in the INS gene. In most animals including humans, a single gene for insulin is found. The human gene is located on the short arm of chromosome 11 at position 15.5 (11p15.5).

The insulin gene has recently been decoded in its complete form in genomic studies. The human and rat insulin genes have been reproduced and the DNA has been sorted. It has been shown that mouse and rat insulins are identical and have similar gene series and organization, which are similar in genetic series to humans.
