Sexual Motivation

Sexual motivation refers to a person's overall desire for sexual activity. It is an unusual motivation. Generally, among lower animals, the term 'drive' is commonly referred to as sexual motivation. It means a certain internal force drags the animal to be involved in reproductive behavior. On the contrary, humans are not simply driven by any internal force; rather, the sexual motivation in humans is due to several factors such as biological (hormones, genes), environmental (familial upbringing, chemical exposure) and physiological factors (culture, desire) which further determine engagement in sexual activities.

Describe what sexual dimorphism is and why its existence is puzzling.
Why do females usually have the control in selecting mate and explain sexual dimorphism.
Why does sexual dimorphism have important implications for studying human evolution? Explain why and prove it with examples.
Sexual reproduction results in offspring that are genetically different from one another and from their parents. Describe four mechanisms that produce this genetic variation. Do any of these mechanisms occur in asexualreproduction?
In C. elegans there are two sexes: hermaphrodite and male. Sex is determined by the ratio of X chromosomes to haploid sets of autosomes (X/A). An X/A ratio of 1.0 produces a hermaphrodite (XX), and an X/A ratio of 0.5 results in a male (XO). In the 1970s, Jonathan Hodgkin and Sydney Brenner carried out genetic screens to identify mutations in three genes that result in either XX males (tra-1, tra-2) or XO hermaphrodites (her-1). Double-mutant strains were constructed to assess for epistatic interactions between the genes (see table). Propose a genetic model of how the her and tra genes control sex determination.
All of the following are correct about asexual reproduction EXCEPT a) it can create numerous offspring quickly b) the offspring are genetically identical to the parent c) it enables animals living in isolation to produce without a mate d) it is advantageous when the environment is changing and the organisms is stressed.
According to the current scientific understanding of the topic, why is our gender identity is NOT a matter of choice?
What is the expected effect on reproduction on an individual with hormone levels shown above? Identify two physiological changes that will not occur due to the atypical hormone levels shown above. The graph below shows the estrogen and progesterone levels of an individual during a menstrual cycle of 28 days. The top light blue line indicates the progesterone levels and the bottom purple line indicates the estrogen levels. This individual is in luteal phase.This individual can be expected to have low levels of FSH and LH.
What defines our biological sex? What is the distinction between genetic and anatomical sexuality? Explain how chromosomes influence the internal and outward development of the sexual anatomy (hormones and structures). Is there always a correlation between genetic and anatomical sex? What is the reason, or why not? Describe a situation or disorder in which the internal and exterior sexual anatomy of a person do not match and explain how this would occur. Describe how a binary (male/female) model of sex does not reflect reality. What would a more accurate model look like?
What is Asexual reproduction? Explain kindly
There are several different forms/methods of amplexus depending on the environment, body form, and relative dimorphism in the sexes. Sometimes the male will stick himself to the back of the female (called “gluing”), at another times he will straddle over the top. The drawing on the top of the next page shows the different forms. Q24: (please type your answer) What form of amplexus did you see with the Panamanian Golden frogs?
In humans males are heterogametic and females are homogametic. Explain. Are there any examples where males are homogametic and females are heterogametic. Also, describe as to who determines the sex of the unborn child and if temperature plays a role in sex determenination.
