Compare traditional plant-breeding methods withgenetic engineering.
Describe the characteristics of pea plants that make them asuitable organism to study genetically.
Before, plant breeding was done by crossing the genes of two plants with
desirable characteristics. This technique has been successful in producing
improved varieties of crop plants, but it is time consuming and complicated.
Because of genetic engineering, these problems can now be avoided. Plants are
inserted with "super" genes to exhibit improved or better traits compared to
their ordinary counterparts. These plants are therefore called transgenic plants.

- Watermelon Genotypic and Phenotypic Ratio Practice Read the information below. Determine the ratios for phenotype and genotype of each Punnett Square.You may use the example from the Punnett Square worksheet as a guide.A genetic engineer is going to cross two watermelon plants to produce seeds for spring planting. He is breeding for size and wants to have many watermelons with the phenotype for long shape as possible. In watermelons, the allele for short shape is (S) is dominant to the allele for long shape. Determine the Genotypic ratios and phenotypic ratios for each Punnett square. Which cross would yield the highest number of long watermelons?

Your edited obligate apomict plants retains all the CRISPR “machinery” necessary to convert the “sexually reproducing” allele to the “obligate apomict” allele. You plant 100 hectares of your edited obligate apomicts in order to increase seed for sale the following year. Neighboring farms and seed producers are growing many different un-edited sexually reproducing varieties of the crop. If your neighbors plant seed harvested from their crops that was pollinated by your crop, should they expect these seeds to generate apomictic or non-apomictic plants?arrow_forward
- These weeds are growing in a farmer's field. The weeds compete with the soybean plants the farmer grows, so he needs to get rid of them. For a few years, the farmer relies on manually removing the weeds, but that is labor intensive and limits how much crop he can grow. The farmer decided to change his crop to genetically modified soybeans that are herbicide resistant. This allows the farmer to use chemicals to remove the weeds. With this GM soybean, the chemical kills the weeds but does not harm the crop. For many years this works, and allows the farmer to expand his farm and grow more soybeans. But then, one of the farmer's fields has a large weed plant remaining after the field has been sprayed with herbicide. Which of the following is likely the reason the weed has remained? A mutation appeared in one weed plant that made that weed not susceptible to the herbicide O The weed needed to be resistant in order to survive, so it became resistantarrow_forwardThese weeds are growing in a farmer's field.
