Kloniranje hišnih ljubljenčkov – zakaj?

Vsak lastnik hišnega ljubljenčka se sooči z izgubo in žalostjo, ko ga njegov kosmati prijatelj zapusti zaradi bolezni, starosti ali celo nesreče. Nekateri se danes lahko odločijo za kloniranje psa ali mačke, vendar je v zvezi s tem spornih več stvari.

Kelly Anderson je povedala, da je bila zelo žalostna, ko je leta 2017 nepričakovano umrla njena 5-letna mačka Chai. Kmalu po smrti mačke je Kelly poslala njen vzorec DNK podjetju za kloniranje hišnih ljubljenčkov s sedežem v Teksasu ViaGen Pets. Po štirih letih in zbranih 25.000 dolarjev je dobila klon mačke, ki jo je poimenovala Belle.

Potek kloniranja hišnega ljubljenčka

  • Za kloniranje potrebuje podjetje ViaGen Pets majhen vzorec kože, ki ga lahko odvzamejo, ko je žival še živa, ali v petih dneh po smrti hišnega ljubljenčka.
  • Vzorec tkiva pošljejo v laboratorij, kjer vzgojijo na milijone celic.
  • Potem pa združijo jajčece živali darovalca in vzgojene celice, da zarodek začne rasti.
  • Zarodek vstavijo v nadomestno žival, ki jo bo donosila, skotila, dojila in skrbela za klon, dokler ga ne prevzame lastnik.
  • Nadomestna žival ima običajno eno ali dve legli, potem jo sterilizirajo in oddajo v posvojitev.
  • Večina legel je majhnih, en ali dva potomca, a včasih je tudi več klonov iz enega legla.
  • V podjetju ViaGen Pets, evtanazirajo klone le, če so skoteni z zdravstvenimi težavami, ki ogrožajo življenje.
  • Čeprav so kloni genetske kopije, pri nekaterih kloniranih živalih obstajajo majhne razlike npr v barvi dlake.
  • Več nejasnosti je še pri prenosu osebnosti in značaja psa ali mačke na klon. Nekateri pri klonu opazijo tudi spremembo značaja.
  • Danes je cena za kloniranje mačke 35.000 dolarjev in 50.000 dolarjev za psa.

The Humane Society of US ne priporoča kloniranja vašega ljubljenčka in opozarjajo na milijone živali, ki potrebujejo ljubeč dom. Izguba hišnega ljubljenčka je lahko priložnost za srečanje z novo živaljo.

_hjClosedSurveyInvites Hotjar cookie. This cookie is set once a visitor interacts with a Survey invitation modal popup. It is used to ensure that the same invite does not re-appear if it has already been shown. 365 days _hjDonePolls Hotjar cookie. This cookie is set once a visitor completes a poll using the Feedback Poll widget. It is used to ensure that the same poll does not re-appear if it has already been filled in. 365 days _hjMinimizedPolls Hotjar cookie. This cookie is set once a visitor minimizes a Feedback Poll widget. It is used to ensure that the widget stays minimizes when the visitor navigates through your site. 365 days _hjDoneTestersWidgets Hotjar cookie. This cookie is set once a visitor submits their information in the Recruit User Testers widget. It is used to ensure that the same form does not re-appear if it has already been filled in. 365 days _hjIncludedInSample Hotjar cookie. This session cookie is set to let Hotjar know whether that visitor is included in the sample which is used to generate funnels. 365 days _hjShownFeedbackMessage This cookie is set when a visitor minimizes or completes Incoming Feedback. This is done so that the Incoming Feedback will load as minimized immediately if they navigate to another page where it is set to show. 365 days _hjid Hotjar cookie. This cookie is set when the customer first lands on a page with the Hotjar script. It is used to persist the Hotjar User ID, unique to that site on the browser. This ensures that behavior in subsequent visits to the same site will be attributed to the same user ID. 365 days _hjRecordingLastActivity This should be found in sessionStorage (as opposed to cookies). This gets updated when a visitor recording starts and when data is sent through the WebSocket (the visitor performs an action that Hotjar records). Session hjTLDTest When the Hotjar script executes we try to determine the most generic cookie path we should use, instead of the page hostname. This is done so that cookies can be shared across subdomains (where applicable). To determine this, we try to store the _hjTLDTest cookie for different URL substring alternatives until it fails. After this check, the cookie is removed. Session _hjUserAttributesHash User Attributes sent through the Hotjar Identify API are cached for the duration of the session in order to know when an attribute has changed and needs to be updated. Session _hjCachedUserAttributes This cookie stores User Attributes which are sent through the Hotjar Identify API, whenever the user is not in the sample. These attributes will only be saved if the user interacts with a Hotjar Feedback tool. Session _hjLocalStorageTest This cookie is used to check if the Hotjar Tracking Script can use local storage. If it can, a value of 1 is set in this cookie. The data stored in_hjLocalStorageTest has no expiration time, but it is deleted immediately after creating it so the expected storage time is under 100ms. N/A _hjptid This cookie is set for logged in users of Hotjar, who have Admin Team Member permissions. It is used during pricing experiments to show the Admin consistent pricing across the site. Session _hjAbsoluteSessionInProgress The cookie is set so Hotjar can track the beginning of the user's journey for a total session count. It does not contain any identifiable information. 30 minutes
