words only definitions & notes
  1. hybridisation
    (genetics) the act of mixing different species or varieties of animals or plants and thus to produce hybrids
    It can also detect genetic pollution, a situation which arises through hybridisation and makes a tiger unsuitable for use in a captive breeding programme -- plus it can be used to establish where a tiger skin may have been misidentified.
  2. subspecies
    a taxonomic group that is a division of a species
    Studbooks are kept for each tiger subspecies and the history of each animal carefully tracked.
  3. purebred
    bred for many generations from member of a recognized breed or strain
    From the testing that has been carried out to date a reasonable number of purebred tigers have been discovered.
  4. genetic
    relating to the study of heredity and variation in organisms
    Genetic testing can show how closely related each animal is to another, whether or not they are suitable breeding partners and what, if any, undesired outcomes there are likely to be.
  5. cleft palate
    a congenital fissure of the hard palate
    It results in serious problems including blindness, cleft palate, sway backs and crossed eyes.
  6. inbred
    normally existing at birth
    The ability of a small inbred group of wild tigers to fight off a sudden virus can reduce to such an extent that catastrophic loss of the population occurs in the event of illness.
  7. bloodline
    ancestry of a purebred animal
    She was then transferred to another zoo to continue the bloodlines.
  8. genetics
    the study of heredity and variation in organisms
    Use of genetics in captive breeding:
    No matter which category an animal falls into biologists must know they're breeding for stability and health.
  9. biologist
    a scientist who studies living organisms
    Use of genetics in captive breeding:
    No matter which category an animal falls into biologists must know they're breeding for stability and health.
  10. genetically
    by genetic mechanisms
    Testing privately owned tigers:
    Recent efforts have been made to encourage private owners to have their tigers genetically tested.
  11. immune system
    the cells in the body that work together to fight disease
    Ultimately, inbreeding leads to weakened immune systems and lowered rates of cub survival.
  12. catastrophic
    extremely harmful; bringing physical or financial ruin
    The ability of a small inbred group of wild tigers to fight off a sudden virus can reduce to such an extent that catastrophic loss of the population occurs in the event of illness.
  13. side effect
    a secondary and usually adverse effect of a drug or therapy
    The population numbers no longer exist to breed without high probability of some undesirable side effects.
  14. sampling
    (statistics) the selection of a suitable sample for study
    Testing wild tigers:
    A recent discovery which came about after genetic sampling was that the Bengal tigers located in Dudhwa Tiger Reserve are not of pure stock.
  15. sample
    a small part intended as representative of the whole
    Testing wild tigers:
    A recent discovery which came about after genetic sampling was that the Bengal tigers located in Dudhwa Tiger Reserve are not of pure stock.
  16. pollution
    contamination of the natural environment
    It can also detect genetic pollution, a situation which arises through hybridisation and makes a tiger unsuitable for use in a captive breeding programme -- plus it can be used to establish where a tiger skin may have been misidentified.
  17. gene
    part of DNA controlling physical characteristics and growth
    India spends about US$75 million a year to protect its tigers and maintain genetic purity, yet hair sample testing on two tigers in this area revealed Amur genes.
  18. DNA
    material that carries genetic information in a cell
    This is not a practice that hurts the animal and DNA tests can be run from gathering up naturally shed hair, stool samples, or blood obtained during routine examinations.
  19. immune
    of the condition in which an organism can resist disease
    Ultimately, inbreeding leads to weakened immune systems and lowered rates of cub survival.
  20. palate
    the surface of the mouth separating oral and nasal cavities
    It results in serious problems including blindness, cleft palate, sway backs and crossed eyes.
  21. conservation
    careful management of the environment and natural resources
    Newly discovered purebred cats can assist in the conservation of the tiger as a whole as some can be used for breeding; this then extends the gene pool.
  22. natural history
    the scientific study of plants or animals (more observational than experimental) usually published in popular magazines rather than in academic journals
    The mounted tiger on this page was originally identified in a Natural History Museum as a Caspian/Amur cross.
  23. Chinese
    of or pertaining to China or its peoples or cultures
    The South Chinese tiger:
    The South Chinese tiger subspecies is extremely inbred, both in the wild and in captivity.
  24. virus
    infectious agent that replicates itself within living hosts
    The ability of a small inbred group of wild tigers to fight off a sudden virus can reduce to such an extent that catastrophic loss of the population occurs in the event of illness.
  25. probability
    a measure of how likely it is that some event will occur
    The population numbers no longer exist to breed without high probability of some undesirable side effects.
  26. plus
    on the positive side or higher end of a scale
    It can also detect genetic pollution, a situation which arises through hybridisation and makes a tiger unsuitable for use in a captive breeding programme -- plus it can be used to establish where a tiger skin may have been misidentified.
  27. illness
    impairment of normal physiological function affecting part or all of an organism
    The ability of a small inbred group of wild tigers to fight off a sudden virus can reduce to such an extent that catastrophic loss of the population occurs in the event of illness.
  28. specimen
    a bit of tissue or fluid taken for diagnostic purposes
    In the normal scheme of things a living specimen of this animal would not be able to be listed in either the Caspian or the Amur studbook, since it is neither one nor the other.
  29. combination
    the act of bringing things together to form a new whole
    The skin is now identified as a Manchurian(Amur)/Bengal cross, a much more likely combination.
  30. normal
    being approximately average or within certain limits
    In the normal scheme of things a living specimen of this animal would not be able to be listed in either the Caspian or the Amur studbook, since it is neither one nor the other.
