a.

Summary Introduction

To determine:

Whether the burnsi phenotype is most likely to be inherited as a dominant or recessive trait.

Introduction:

The heterozygosity is the presence of two different alleles of a particular gene in a particular species. The dominant and recessive gene describes the inheritance pattern. The dominant allele can be expressed either in homozygous or heterozygous condition while the recessive allele expressed only in homozygous condition (in absence of dominant allele).

b.

Summary Introduction

To determine:

The genotypes of the parent in each given cross (use B for the burnsi allele and ${\text{B}}^{+}$ for pipiens allele).

Introduction:

The heterozygosity is the presence of two different alleles of a particular gene in a particular species. The dominant and recessive gene describes the inheritance pattern. The dominant allele can be expressed either in homozygous or heterozygous condition while the recessive allele expressed only in homozygous condition (in absence of dominant allele).

c.

Summary Introduction

To determine:

The fit of the observed numbers of progeny to the number expected on the basis of proposed genotypes by using chi-square test.

Introduction:

The heterozygosity is the presence of two different alleles of a particular gene in a particular species. The dominant and recessive gene describes the inheritance pattern. The dominant allele can be expressed either in homozygous or heterozygous condition while the recessive allele expressed only in homozygous condition (in absence of dominant allele).
