Question
Chapter 12, Problem 5PDT
Summary Introduction
To determine: The differences between the behavior of females in a haplodiploid species (such as ants) and females of diploid species (such as beetles) toward their brothers.
Introduction: Haplodiploid species are those which generally do not produce their own offsprings but help their sisters and brothers (siblings) to produce viable offsprings. Diploid species comprise members that are able to produce fertile offsprings by themselves.

What are the advantages and disadvantages of the alternation between fertilization and meiosis in sexually reproducing organism?
Why is meiosis necessary in sexual reproducing organisms?
Do all dioecious species have a homogametic and a heterogametic sex?
1. Yes, because dioecious means that two types of gametes are produced, even in hermaphroditic species.
2. Yes, because all sex-determining systems include heterogametic and homogametic sexes.
3. Yes, because in dioecious organisms, either the XX-XY or the ZZ-ZW system determines sex. XY and ZW individuals are heterogametic. XX and ZZ individuals are homogametic.
4. No, because hermaphrodites and species that reproduce asexually are dioecious.
5. No, because dioecious means that the sexes are separate, regardless of how sex is determined. In some dioecious species, sex is determined by a single gene.
