This unusually lengthy mating is due to the physical nature of the male's erect penis, which has backwards-pointing spines along most of its length. [20] Fossa mating includes a copulatory tie, [15] which may be enforced by the male's spiny penis. [20] The tie is difficult to break if the mating session is interrupted. [15]
Sex differences in human physiology are distinctions of physiological characteristics associated with either male or female humans. These differences are caused by the effects of the different sex chromosome complement in males and females, and differential exposure to gonadal sex hormones during development. Sexual dimorphism is a term for the ...
Sex differences in human physiology are distinctions of physiological characteristics associated with either male or female humans. These can be of several types, including direct and indirect, direct being the direct result of differences prescribed by the Y-chromosome (due to the SRY gene ), and indirect being characteristics influenced ...
The relationship between sex differences in the brain and human behavior is a subject of controversy in psychology and society at large. [ 118 ] [ 119 ] Many females tend to have a higher ratio of gray matter in the left hemisphere of the brain in comparison to males.
The human Y chromosome showing the SRY gene which codes for a protein regulating sexual differentiation. Sexual differentiation in humans is the process of development of sex differences in humans. It is defined as the development of phenotypic structures consequent to the action of hormones produced following gonadal determination. [1]
The Malagasy or striped civet (Fossa fossana), also known as the fanaloka (Malagasy, [fə̥ˈnaluk]) or jabady, [5] is an euplerid endemic to Madagascar. [6] It is the only species in genus Fossa . The Malagasy civet is a small mammal , about 47 centimetres (19 in) long excluding the tail (which is only about 20 centimetres (7.9 in)).
Sex differences in medicine include sex-specific diseases or conditions which occur only in people of one sex due to underlying biological factors (for example, prostate cancer in males or uterine cancer in females); sex-related diseases, which are diseases that are more common to one sex (for example, breast cancer and systemic lupus erythematosus which occur predominantly in females); [1 ...
The fossa (Cryptoprocta ferox) is a smaller relative of C. spelea that still survives.. Although some morphological differences between the two fossa species have been described, [17] these may be allometric (growth-related), and in their 1986 Mammalian Species account of the fossa, Michael Köhncke and Klaus Leonhardt wrote that the two were morphologically identical.
