Chapter 7, Problem 11RQ
Summary Introduction
To distinguish: Two kinds of mammalian reproductive cycles called the estrous and menstrual cycle.
Introduction: Reproduction is the biological process through which the new individual organism is produced from their parents. The reproductive structures of both male and female are divided into two types namely, internal and external organs. Both functions together in the development of the reproductive cells.

Students have asked these similar questions
How do the two kinds of mammalian reproductive cycles— estrous and menstrual differ?
What are the general characteristics of sexual reproduction in humans and other vertebrates that are associated with continuous production of many sperm cells but intermittent, finite production of egg cells?
Asexual reproduction passes on 100% of the parent's genes but it is relatively rare.
What are the advantages of sexual vs asexual reproduction? In some cases, species
are hermaphrodites to reduce the difficulty in finding mates. What is the difference
between simultaneous and sequential hermaphrodites? Why is "selfing" relatively
rare?
