A B 14. A genetic bottleneck describes a situation when alarge population is reduced to few breeding members resulting in reduced genetic diversity Solution 14 .A genetic bottle neck described a situation when a large population is reduced to few breeding members resulting in reduced genetic diversity----------false ============================================================ 15 .Taxonomy is the scientic field that established the rules of biological classification-correct It includes both nomenclature and classification.. ======================================================= 16.cladistics is a classification systems …. ....homologous charatcers—FALSE ======================================================= 17 . in modern classification system a clase is group of organism who share a common ancestor—TRUE =============================================================== 18 . Pangea was an early mammal like reptile living during the mesozoic era……true ======================================= 19. coenozonic era along with birds replaced earlier replaced reptiles.--------true ============================================================== 20 false Mammals are heterodont :teeth are incisors, canines, premolars, and molars ================================= 21. homeotic box genes are evolutionarily ancient critically important type of regulatory gene --- true ================================================ Populace bottlenecks happen when a populace\'s size is diminished for no less than one era. Since hereditary float acts all the more rapidly to decrease hereditary variety in little populaces, experiencing a bottleneck can lessen a populace\'s hereditary variety by a considerable measure, regardless of the possibility that the bottleneck doesn\'t keep going for a lot of eras. This is represented by the sacks of marbles demonstrated as follows, where, in era 2, a strangely little draw makes a bottleneck. ======================================= A KEY FEATURE OF CLADISTICS IS THAT GROUPS OF ORGANISMS ARE DEFINED BY SYNAPOMORPHIES. THESE ARE MONOPHYLETIC GROUPS. THERE ARE OTHER KINDS OF GROUPS, THOUGHT TO BE MUCH LESS DESIRABLE BY CLADISTS, THAT ARE DEFINED BY HAVING MEMBERS SHARING OTHER KINDS OF CHARACTERS THAN SHARED DERIVED ONES. ====================================================== In transformative formative science, homeotic gene are qualities which direct the improvement of anatomical structures in different creatures, for example, creepy crawlies, well evolved creatures, and plants.
