Summary Introduction

To review:

The difference between the gastrulation in reptiles and amphibians.

Introduction:

The cells of the blastula undergo complex movements to form the three germ layers: ectoderm, mesoderm, and endoderm, from the outside to the inside. This process is known as gastrulation, and it leads to the formation of a structure known as the gastrula. It is also responsible for establishing the anterior-posterior axis of the body.

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
A sample of blood was taken from the above individual and prepared for haemoglobin analysis. However, when water was added the cells did not lyse and looked normal in size and shape. The technician suspected that they had may have made an error in the protocol – what is the most likely explanation?   The cell membranes are more resistant than normal.   An isotonic solution had been added instead of water.   A solution of 0.1 M NaCl had been added instead of water.   Not enough water had been added to the red blood cell pellet.   The man had sickle-cell anaemia.
