Chapter 18, Problem 3P
Summary Introduction

a.

To determine:

The results that would be expected if a laser is used to destroy one of the four cells of the embryos of early C. elegans and early mouse.

Introduction:

The model organisms are non-human species that help researchers to understand biological processes. They are generally easy to cultivate and rapidly produce a large number of progenies.

Summary Introduction

b.

To determine:

The results that might be expected if the four cells of the embryo are separated from each other and allowed to develop.

Introduction:

Organisms may use different strategies to accomplish the same developmental goal. For example, early C. elegans embryos show mosaic determination and early mouse embryos show regulative determination.

Summary Introduction

c.

To determine:

The multicellular organism exhibit countless strategies for development during the course of evolution. It creates a difference between mosaic and regulative determination patterns of development.

Introduction:

The model organism is easy to grow, and they quickly give birth to a large number of progenies. Therefore, geneticists can find rare mutations and study their behavior through successive generations.

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
