How is sexual selection different from natural selection, and why are the reproductive strategies of males and females different?
Homework Answers
Natural selection means a process in which organism adapted to their environment and produce offspring for increasing their population.
Sexual selection include selection based on mate choice. In this, males and females require certain character in their mate based on which they select them.
Females select those males which give better fitness genes to their offspring for adapting in environment with greater diversity.
Mainly Males see those female who can care their offspring well

Compare and contrast natural selection and sexual selection. What is the difference between intersexual and intrasexual selection?

How does the degree of sexual dimorphism in traits like these relate to the social organization of a particular species?

1) Sexual selection usually acts more strongly on males, i.e., males compete with other males for access to females, and females choose among potential male mates. Give one specific example of role-reversed mate choice (the male chooses among females) (1). What kinds of female traits do males base their choice on (1)? What types of benefits do males receive (1)? How does this differ from female mate choice (2)? Please help!

(a) Sexual selection often leads to sexual dimorphism; this sometimes results in males being more colourful. Explain this under the good genes hypothesis (b) Focusing on males what is this type selection an example of (stabilising, directional or disruptive)? (c) Thinking about males and females what type of selection is this?
