Generally,complex Organisms Do Require More Genes to Control Their Synthesis

question 2

Multiple Choice

Generally,complex organisms do require more genes to control their synthesis and organization than do primitive organisms.However,the numbers of chromosomes vary from ants with 2,molds with 8-14,humans with 46,potatoes with 100 and the crayfish with 200! Some birds and insects have chromosomes that dwindle in size into obscurity,so it is not possible to establish a diploid number.How do you explain this situation?

• A)there must be no relationship between amount of genetic information and complexity of the organism.
• B)the number of genes per chromosome may vary among organisms,preventing a simple relationship between chromosome number and complexity.
• C)birds and insects probably cannot follow the same mitotic laws as other organisms.
• D)All of the choices are correct.
