In this lesson we'll learn about the techniques scientists use in plant breeding to benefit food production. By the end of the lesson, you'll be able to explain how scientists do this and give examples of food sources produced in these ways. ...

An example of true breeding would be a tall, purple plant that has the genotype PPTT. Anytime the plant is crossed to itself, or another plant of the same genotype, the phenotype of the offspring will match the parents. In this case, all offspring would be purple and tall.What...
In animals, hybrid offspring of two different species are thought to be unhealthy or infertile as adults, but in plants hybrid offspring are often thought to be more vigorous than their parents. As a result, plant biologists and animal biologists differ regarding the significance of interbreeding ...
The majority of plants are actually hermaphrodites, where a single plant will contain a flower that is male and consists of the male reproductive organs and a flower that is female and contains the female reproductive organs. In some special species, there is what is termed mixed-breeding. The...
Herbivores (including rabbits and cows) cannot survive without bacteria in their guts to break down indigestible plant materials into nutrients a cow can use. It then digests the nutrients and some of the bacteria.How is this symbiotic? Because the food eaten by the herbivore becomes food for ...
Another example is the mating between two dogs of the same breed. The traits of the resulting offspring would therefore be more predictable. With plants, true breeding occurs when plants produce only offspring of the same variety when they self-pollinate. For instance, a plant that has blue ...
Plant response to a stress may be very different depending upon the timing of the stress relative to the plant life cycle. In addition, stresses may interact differently depending upon time of season. Our ability to estimate reductions in growth, development, and subsequently, yield resulting from...
