Exploring the Intricacies of Selective Breeding, Inbreeding, and Hybridization

This article delves into selective breeding, inbreeding, and hybridization, illustrating how these practices shape the genetic characteristics of various animals and plants. Through specific examples like sled dogs, racehorses, and bananas, we explore how selective breeding creates desired traits. Inbreeding maintains pure breeds in species like dogs and cattle, while hybridization merges unique traits from different organisms, leading to fascinating hybrids such as the churkey and zorse. Understanding these concepts reveals the complexity of genetic manipulation in agriculture and animal breeding.

  1. Tinkering with Inheritance By Chase, Robert, and Zach

  2. Selective Breeding • Selective Breeding is when breeding specific animals together to get the desired traits for the next generation • An example of Selective Breeding is dogs that are used for sledding, they are bred to be strong and fast

  3. Race Horses • Race Horses are bred to be fast for the competitions • The breeders use selective breeding to make sure they are fast

  4. Bananas • Bananas and other plants are also selectively bred to become better-tasting and easier to eat • Banana trees are also bred to produce more bananas

  5. Inbreeding • Inbreeding is mating closely related species to keep a pure breed of a certain type of species • The purpose is to fix traits in a breed (Specific group of animals

  6. Dogs • Dogs are inbred by breeders commonly to keep the same traits • The breeders like to keep the same pure breed of a dog

  7. Mice • Mice are often inbred in laboratory research • This is done to get consistent data when testing the mice

  8. Cattle • Cattle are inbred to continue on desirable traits within the family

  9. Hybridization • Hybridization is the breeding of two different organisms of two different stocks • It is done to produce a hybrid of both organisms, borrowing desired traits from both stocks

  10. Churkey (Chicken-Turkey) • A “churkey” is a mix between chickens and turkeys • They were hybridized for experimental reasons to see if these two different organism could be hybridized

  11. Crops • Crops are often hybridized • This is because they could be grown more efficiently by resisting disease better, by taking traits from one of the plants mixed into the hybrid

  12. Zorse (Zebra-Horse) • A “Zorse” is a mix between a horse and a zebra • The Zorse was another interesting experiment, however they are sterile
