Question

Which of the following statements regarding genetics is false?

A. About 99% of the genes of humans and mice are related by descent from a common ancestor.
B. Gene duplication helps to explain how mammals can detect and discriminate among such a wide range of odors.
C. In keeping with our greater complexity, the human genome has about 100 times more genes than that of yeast.
D. The more recently two species have branched from a common ancestor, the more similar we expect their DNA sequences to be.

Answer 1

A false statement regarding genetics is that A. about 99% of the genes of humans and mice are related by descent from a common ancestor.

Step-by-step explanation:

The false statement regarding genetics is A. About 99% of the genes of humans and mice are related by descent from a common ancestor.

This statement is incorrect because humans and mice share a common ancestor, but not all of their genes are related by descent from that ancestor.

The similarities in genetic sequences between different species can vary and are not always directly related to the degree of similarity in their DNA sequences.
