Chapter 14, Problem 10TYU

To determine: Whether the curl allele is dominant or recessive in the first curl cat.

Summary Introduction

Concept introduction:

Genes have alternate forms known as alleles, which are transmitted to the offspring. If the offspring receives the same phenotypic traits of the parents, then it is known as true-breeding. If the two alleles are different, then there is a hybrid at F1 generation. The dominant allele out of the two alleles expresses itself and determines the phenotype. In F1 individuals, two different alleles segregate into gametes. During self-fertilization, the gametes unite randomly thereby having a chance for recessive allele to be expressed in the homozygous state at F2 generation.

You intend to insert patched dominant negative DNA into the left half of the neural tube of a chick.  1) Which side of the neural tube would you put the positive electrode to ensure that the DNA ends up on the left side?  2) What would be the internal (within the embryo) control for this experiment?  3) How can you be sure that the electroporation method itself is not impacting the embryo?  4) What would you do to ensure that the electroporation is working?
