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.

Sometimes gene flow between populations can have negative effects, with one population receiving genes of lower fitness from another population.

The original source of new alleles, upon which selection operates,is mutation, a random event that occurs without regard to selectionalvalue in the organism. Although many model organismshave been used to study mutational events in populations, someinvestigators have developed abiotic molecular models. Soll et al.(2006. Genetics 175:267–275) examined one such model to studythe relationship between both deleterious and advantageousmutations and population size in a ligase molecule composed ofRNA (a ribozyme). Soll found that the smaller the population ofmolecules, the more likely it was that not only deleterious mutationsbut also advantageous mutations would disappear. Whywould population size influence the survival of both types ofmutations (deleterious and advantageous) in populations?
Imagine that you are a conservation biologist responsible for the well-being of a bufello herd consistingof 100 mature males and 100 mature females. In this herd, there is no appreciable mutation, there isno migration in or out, and there is no selection. At the Fuzzy gene locus, there are two alleles, G and E.Homozygous G individuals have fuzzy fur, homozygous E individuals have rough fur, and heterozygoteshave shaggy fur. Suppose you survey the herd and find that there are 44 fuzzy individuals, 72 shaggyindividuals, and 84 rough individuals.a)What is the size of the population?b)Do the alleles have a simple dominance relationship? Describe.c)What are the frequencies of the two alleles?d)Is the population in Hardy-Weinberg equilibrium?If not, how do you know, and what might be the cause?
In a population of lizards, color is genetically determined. The current population has two two phenotypes: blue and yellow. Which of the following scenarios could result in evolution by migration? O A disease indiscriminately reduces the population by 90%. Birds are better able to see and therefor prey on blue lizards The population is joined by individuals from a nearby population that has an allele for a red phenotype. Females preferentially mate with individuals exhibiting the blue phenotype.

Skin colour in dolphins is determined by a single gene showingincomplete dominance giving rise to 3 phenotypes Brown, Pink &White. A survey of a large population of dolphins was carried outand the phenotypes recorded. However a student who had some.of the data stored on their phone fell overboard and unfortunatelythe data was lost. The only data saved was that the brownhomozygous dominants (BB) were 64% of the population.a) What would be the percentage of pink heterozygotes and whitehomozygotes?b) What percentage of the gametes that give rise to the nextgeneration of dolphins in this population will contain the b allele?
Consider the first copy of an allele for insecticideresistance that arises by mutation in a populationof insects exposed to an insecticide. Is this mutation an adaptation? If, after some generations,we find that most of the population is resistant,is the resistance an adaptation? If we discovergenetic variation for insecticide resistance in apopulation that has had no experience of insecticides, is the variation an adaptation? If an insectpopulation is polymorphic for two alleles, eachof which confers resistance against one of twopesticides that are alternately applied, is thevariation an adaptation? Or is each of the tworesistance traits an adaptation?
