السؤال 11

In a note on DNA, genes and chromosomes, one statement about chromosome numbers is false. Which statement is it?

Different species can have different numbers of chromosomes
Chromosome number does not change as an organism grows
Two different species may happen to have the same chromosome number
Counting the chromosomes tells you how advanced a species isالإجابة الصحيحة

الشرح

Chromosome number varies from species to species without tracking complexity, so it cannot be used to rank organisms. Species most people would call simple can carry more chromosomes than species people call complex, which is exactly why the count says nothing about how advanced anything is.
