(a)

Summary Introduction

To determine: The meaning of maternal effect genes.

Introduction: Development of an organism at the cellular level is marked by the process of specification, differentiation, and development. Various genes are involved in the proper development of an embryo.

(b)

Summary Introduction

To determine: The period of development of gene products of maternal effect genes and their location.

Introduction: The development in Drosophila is maintained by the zygotic genes and maternal effect genes. Maternal effect genes regulate the early embryonic development in an organism.

(c)

Summary Introduction

To determine: The aspects of development that are controlled by maternal effect genes.

Introduction: As mentioned in the concept introduction part (b).

(d)

Using information from the primary literature (several references have been provided as a starting point below) please answer the following question: Based on your review of the literature on rewilding, what are the major scientific pros and cons for rewilding?   Please note that the focus of this assignment are the (biological) scientific issues associated with rewilding. As will be discussed in class, there are a number of non-scientific issues involved or implicated in rewilding, all ultimately affecting the public acceptability of rewilding. Although these issues are important – indeed, critical – in this assignment you should focus on the biological science issues and questions.   Details: You must enumerate at least two pros and at least two cons. Your answer should be no more than 500 well-chosen words, excluding references. Think carefully about how best to organize and structure your answer. Aim for high information density: say a lot, but say it succinctly. Recall Nietzche’s…
