Summary Introduction

To review:

The concerns related to GM (genetically modified) crops that contain foreign (non-crop plant) genes.

Introduction:

The GM crops are the plants whose DNA (deoxyribonucleic acid) has been altered using biotechnological techniques. The aim of producing the GM crops is to introduce new traits in the plant that are naturally absent in them to produce specific biological product and increase crop productivity.

Transgenic plants usually contain genes of bacterial plasmid origin. In a study, researchers transformed cells from a susceptible potato variety with a potato blight resistance gene cloned from a resistant variety. They performed PCR using primers specific for the plasmid to determine which plants from this group were also free of plasmid DNA (cloning vector) sequences. The positive control lane showed PCR amplification of plasmid DNA only, and the negative control lane showed an attempted PCR amplification of no added DNA. Use this study to address concerns related to GM crops.

You implant an FGF10-coated bead into the anterior flank of a chicken embryo, directly below the level of the wing bud. What is the phenotype of the resulting ectopic limb?  Briefly describe the expected expression domains of 1) Shh, 2) Tbx4, and 3) Tbx5 in the resulting ectopic limb bud.
Design a grafting experiment to determine if limb mesoderm determines forelimb / hindlimb identity. Include the experiment, a control, and an interpretation in your answer.
The Snapdragon is a popular garden flower that comes in a variety of colours, including red, yellow, and orange. The genotypes and associated phenotypes for some of these flowers are as follows: aabb: yellow AABB, AABb, AaBb, and AaBB: red AAbb and Aabb: orange aaBB: yellow aaBb: ? Based on this information, what would the phenotype of a Snapdragon with the genotype aaBb be and why?   Question 21 options:   orange because A is epistatic to B   yellow because A is epistatic to B   red because B is epistatic to A   orange because B is epistatic to A   red because A is epistatic to B   yellow because B is epistatic to A
