Question
Mitochondria originated from bacteria cyanobacteria mycoplasmas chlamydia's D proteobacteria An aggregate of all alleles in a population is microevolution genome macroevolution gene pool After separation from chimpanzee line first in human phylogeny is A)Australopithecus Africans B Australopithecus afarensis C Adipates raids Homo hails New taxon's suddenly appear in geological strata due to adaptive radiation convergent evolution mass extinction genetic drift Nitrogen fixing bacteria in legume roots Bacillus anthracis Helicobacter pylori Rhizobium cyanobacteria Distinguish between Bacteria, Archaea and Eukarya domains. What is continental drift? Mention its role in evolution. Distinguish between gram and gram Describe main steps of microevolution. A fruit fly population has 70% dominant allele for a particular gene. What proportion is carried by individuals with heterozygous alleles if population is in Hardy-Weinberg equilibrium? Plant species A has 10 and plant species B has 12 chromosomes. Show the origin of a new species by polyploidy from species A and B. What are variations? Describe main types. Explain origin of eukaryotic cell from a prokaryotic ancestor. Describe 3 types of natural selection. Give one example each. Describe 2 prezygotic and 2 postzygotic barriers. Draw the phylogenetic tree for 5 groups of domain bacteria.Explanation / Answer
Answer=mitochondria originated from bacteria
D ] Probacteria
Explaination = endosymbiont theory is now a days most accepted theory of origin of mitochondria
phylogenetic analysis performed on bacterial & mitochondrial small subunit rRNA i.e. 16 rRNA sequences done by carl woese identified alphaprobacteria
much evidence support that mitochondrial genome originate from bacterial phyla the alphaprobacterial are the closest identified relatives of mitochondria from phylogenetic analysis of both protein coding gene & ribosomal genes r RNA specified by mitochondrial DNA
