Biotechnology Breeding Methods Quiz

Cross breeding involves combining two sexually compatible species to create a variety with the desired traits of the parents. An example is the honeycrisp apple, which blends the traits of its parents to achieve its famous texture and flavor.

Mendel's work on heredity in pea marked the beginning of the science of genetics by establishing the rules of heredity. It led to the discovery of DNA and the understanding of genetic mechanisms, linking genetic elements with phenotypic characteristics.

Genetic engineering is a technique used for the manipulation of genes, enabling new combinations of genetic material to be constructed in a laboratory. It relates to crop improvement by allowing the modification or optimization of genes for expression in different cell systems, creating artificial genes for specific phenotypes.

<p>Polyploidy is the multiplication of the number of chromosomes in a crop, impacting its fertility. It can lead to changes in the genetic makeup of the crop, potentially resulting in improved characteristics such as increased yield or disease resistance.</p> Signup and view all the answers

<p>Mutagenesis is the use of mutagens such as radioactivity to induce random mutations, creating the desired trait. It is used in crop modification to induce mutations that lead to the development of desired traits, such as using radiation to produce a deeper color in the red grapefruit.</p> Signup and view all the answers
