The parental sex selection behaviour of altruistic parents without gender specific preference in a monogamous marriage market is studied. Using an OLG model with intra-household resource allocation determined by marriage market bargaining, we find that the equlibrium with a balanced male/female ratio is unstable. Depending on the effect of the marriage market sex ratio on intra-household alloca...

In previous research the inheritance patterns of synaesthesia (eg experiencing colours from graphemes) has been studied and it was concluded that synaesthesia is most likely to be the outcome of a single gene passed on the X chromosome in a dominant fashion. In addition, it has been reported that the female-male ratio of synaesthetes is as high as 6:1 and the families of synaesthetes contain mo...

Adolescents and adults show preferences for male and female body shapes consistent with evolutionary theories of reproductive fitness and mate selection. However, when these preferences for females with narrow waists (i.e., 0.7 waist-to-hip ratio) and men with broad shoulders (i.e., mesomorphic body shape) emerge during the lifespan is largely unknown. To address this knowledge gap, eye-movemen...

conclusions the extract contains substances that are effective on the delivery rate, sex ratio, and the number of newborns in the female rats. it may affect through the ionic changes in the rats, by modifying the activity of follicle-stimulating and testosterone hormones, and/or changing the rate of fertilizing ability of sperms containing y chromosome. this phenomenon may also be due to loweri...

The Alzheimer's Association recently reported that a woman's estimated lifetime risk of developing Alzheimer's at age 65 is 1 in 6, compared to nearly 1 in 11 for a man (ie, female to male ratio 1.8). Based on female to male ratio, Alzheimer's disease could well be an autoimmune disorder. Like Alzheimer's, multiple sclerosis, an autoimmune inflammation of the central nervous system, has a femal...
