Summary Introduction
Introduction:
Male species of any organism is different from female specie of the other organism. It is due to the differences in their genes. Genes are the governing factor of each and every trait in all the organisms. There is a theory called the sexual selection. This theory is a type of natural selection and was proposed by Charles Darwin and Alfred Russell.

- A male and female gibbon that are similar in size likely demonstrate the lack of sexual dimorphism… A : due to the polygamous social structure in gibbons. B : as the result of unequal access to resources within their environment. C : which is not related to social structure in gibbons. D : due to adaptations related to Allen’s rule. E : due to decreased competition for mates in a monogamous social structure.arrow_forwardWhy are polyandrous mating systems more rare than polygynous matings? a. Only males are capable of multiple rounds of reproduction within a single breeding season. b. Only females care for the young. c. Females usually experience more intrasexual selection pressure than males. d. Females usually devote more energy to offspring production and development.arrow_forwardClassify these variations as to "species characteristics" or "individual characteristics". a.

- Is sexual selection or natural selection the driver for the differences between males and females? a. In the hollyhock weevil (Rhopalapion longirostre) the females a have much longer rostrum. The length of rostrum is correlated with offspring survival but not mating frequency. b. In the marine iguana species (Amblyrhynchus cristatus) on the islands near Ecuador the males often exceed expected size on a given island. Male size is correlated with survival and number of mating events.arrow_forwardAn orchid species has flowers that resemble and smell like female bumblebees. The flower attracts male bumblebees, which attempt to mate with the flower. They get a package of pollen attached to their body, which they then deliver to another orchid flower of the same species. Which of the following statements about this is correct? a. this is an example of mullerian mimicry b. this is an example of batesian mimicry c. this appears to be a different type of mimicary rhat does not fit either mullerian or batesian model d. no answer text providedarrow_forwardDescribe the feeding biology of centipedes, spiders, mites and beetles.

- How would self-sacrifice of male redback spiders be an adaptive behaviour? Select one: a. When males meet a female and self-sacrifice, it activates enzymes that make his sperm more fit and able to fertilize more eggs. b. Males are able to mate with one female, then mate with another female nearby, before being devoured by the first female. C. Males only use self-sacrificing behaviour once they have mated with several females and have exhausted their sperm supplies. d. The chance of a male meeting more than one female is quite low; self-sacrifice maximizes mating time with and sperm transfer to any female the male finds.arrow_forwardMammals are distinguished from other animals based ona. size and hair type.b. mode of reproduction.c. number of limbs and method of caring for young.d. number of mammary glands and number of offspring.arrow_forward#4: In clown fish (chose one answer) A.
