Summary Introduction

To determine: The definition of zygotic genes and the time during which their gene products are made.

Introduction: The life cycle of Drosophila lasts for 10 days only. The developmental process in Drosophila are controlled by maternal effect genes. During the initial development, the regulation of transcription is done by maternal effect genes.

(b)

Summary Introduction

To determine: The phenotype which is associated with zygotic gene mutations.

Introduction: During the developmental process, cells achieve a variety of structural and function specializations. This results in differential gene expression. Developmental processes are controlled by the cascade of gene expression.

(c)

Summary Introduction

To determine: Whether the maternal genotype contains zygotic genes.

Introduction: Differential gene expression is observed in the case of different developmental processes. These developmental processes are regulated by genes at the transcriptional and post-transcriptional level.

Zygote Embryo Muscle cells Intestinal cells Liver cells Blood cells Nerve cell Cardiac cells (1) Specialization occurs, resulting in the formation of a great variety of cell types. (2) Genes are inserted into the zygote to allow for the formation of different cell types. (3) The expression of genes responsible for the different cell types is controlled by the placenta. (4) The genetic information in the zygote is divided to produce a complete set for each cell type
