Summary Introduction
To determine: The way in which the maternal effect genes, segmentation genes and homeotic genes control the process of development in animals.
Introduction: Regulation of genes is an important part of the expression of genes and is the reason why different genes are expressed differently in different organisms. The homeotic genes, segmentation genes and maternal effect genes help in the regulation of morphological features of the organism through certain transcriptional factors.

- 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.
