The 264 pages that link to Sexual dimorphism, each with the reason it gives.

• Sexual selectionRelated: Different mating pressures can produce conspicuous sex-specific traits.

• DioecyRelated: Separate sexes can evolve distinct forms or resource-allocation strategies in dioecious plants.

• Australopithecus afarensisRelated: Size differences among fossils have informed estimates of this species’ sex-based variation.

• GalliformesRelated: Many galliforms show conspicuous sex differences in size, plumage, or ornamentation.

• Courtship displayRelated: Sex-specific displays often accompany conspicuous differences between the sexes.

• AmplexusRelated: Male forelimb strength and enlarged nuptial pads can help maintain amplexus.

• OrangutanRelated: Adult male orangutans can develop cheek pads and a throat pouch.

• Bird plumageRelated: Plumage differences between the sexes are one visible form of dimorphism.

• UrsidaeRelated: In several bear species, males are substantially larger than females.

• Mate choiceRelated: Repeated mate preferences can produce sex differences in traits.

• PhasianidaeRelated: Distinctive male plumage and size differences occur in many pheasants and related phasianids.

• Sexual conflictRelated: Sex-specific traits can reflect different reproductive pressures, including conflict.

• ConfuciusornisRelated: The long paired tail feathers may have differed by sex, though their function remains debated.

• Mating systemRelated: Mating competition and partner choice can produce sex-specific traits.

• Dosage compensationRelated: Unequal expression of sex-linked genes can contribute to sex-specific traits.

• PheasantRelated: Many pheasants show striking differences in plumage between the sexes.

• Antarctic fur sealRelated: Males grow much larger than females, shaping competition at breeding colonies.

• Wild boarRelated: Adult males typically grow larger and develop prominent tusks.

• PteranodonRelated: Differences in Pteranodon crest size and body proportions have been interpreted as possible sex-related variation.

• Sex-role reversalRelated: Reversed competition can produce female-biased differences in size or ornamentation.

• TigerRelated: Male tigers are generally larger than females, especially in some populations.

• AntlerRelated: In most deer species, antlers occur primarily or exclusively in males.

• BonoboRelated: Bonobo males and females differ less in body size than those of many other apes.

• NematodaRelated: Many nematode species have distinguishable sexes, often with males smaller or differently shaped.

• Rhinoceros hornRelated: Horn size and shape can differ between the sexes in some rhinoceros species.

• Sexual differentiationRelated: Dimorphism describes observed differences, whereas differentiation names the processes producing them.

• AgamidaeRelated: Many agamids show sex-linked differences in coloration, crests, or body size.

• Amazon river dolphinRelated: Males are often larger and more vividly pink than females.

• American black bearRelated: Adult males are generally larger than adult females.

• American minkRelated: Male American mink are generally larger than females.

• Cranial ornamentationRelated: Sex-specific growth can produce different cranial ornamentation.

• Lucy (Australopithecus)Related: Size variation among afarensis fossils, including Lucy, bears on estimates of sex differences.

• MantodeaRelated: In some mantis species, the sexes differ in size, wing form, or body proportions.

• OssiconeRelated: In okapis, the presence of ossicones is generally male-specific.

• Sex-determination systemRelated: Dimorphism describes resulting differences, not the mechanism assigning sex.

• The Descent of ManRelated: Darwin used sex differences in bodies and behavior as evidence of sexual selection.

• Wild turkeyRelated: Male wild turkeys are larger and more ornamented than females.

• Bornean orangutanRelated: Adult males are much larger and develop distinctive cheek pads.

• European bisonRelated: Male wisents are typically larger and more heavily built than females.

• GharialRelated: The ghar is a conspicuous adult-male trait, making the sexes easy to distinguish.

• House sparrowRelated: Male and female house sparrows differ visibly in plumage.

• HylobatidaeRelated: Its degree varies among gibbon species, including differences in coat color.

• LionRelated: The conspicuous male mane is a prominent example in lions.

• PumaRelated: Male pumas are generally larger than females, affecting competition and space use.

• Rhesus macaqueRelated: Male rhesus macaques are generally larger than females, with prominent canine teeth.

• Snake identificationRelated: Sex-related variation can make two members of one species look unexpectedly different.

• Social construction of genderRelated: Bodily differences are often invoked to justify gender arrangements, though they do not dictate them.

• Spotted hyenaRelated: Spotted hyenas show atypical external genital anatomy and limited visible size differences between sexes.

• African lionRelated: Male manes and differences in body size make the sexes conspicuously distinct.

• AntelopeRelated: Horn size, body size, and coloration often differ between antelope sexes.
