To explain: The reason for abandoning of the five kingdom classification system for a three-domain system.
Concept introduction:
Organisms are classified into different taxa or groups based on their genetic data or morphology. A taxon is a single or a group of organisms that are placed in one category. Earlier, biologists placed the organism into the five kingdom system. These are Monera, Protista, Plantae, Fungi, and Animalia. Monera were classified as prokaryotes in the five kingdom classification system. Protista consists of a diverse kingdom that consists of unicellular organisms. But, soon the three domain system came into existence based on information obtained from genetic data. These three domain system includes Bacteria, Archaea, and Eukarya.

Which statement BEST explains how cystic fibrosis is maintained in the gene pool? O A. Organisms that are heterozygous can pass on only the dominant allele. O B. Organisms that are homozygous-dominant pass on either dominant or recessive alleles. O C. Organisms that are heterozygous can pass on the recessive alleles because they are carriers of the disorders but do not show characterisitcs of the disorder becuase they have the dominant allele as well. O D. Organisms that are homozygous-recessive pass on only the dominant allele.arrow_forwardThe goal of many captive breeding programs like zoos is to maintain 90% genetic diversity over 100 years.
