Question

Is an organism that has 100 protein coding genes less complex than one with 10,000?

Answer 1

No, it is not necessary that an organism that has 100 protein coding genes will be less complex than one with 10,000.For example single-celled amoebae have some of the largest genomes i.e almost upto 100-fold larger genome than the human genome but still amoeba is less complex than humans.
