Like many other medical conditions, obesity is the result of an interplay between environmental and genetic factors. [2] [3] Studies have identified variants in several genes that may contribute to weight gain and body fat distribution, although only in a few cases are genes the primary cause of obesity. [4] [5]
The average body weight of women in America has been steadily increasing over the past few decades. According to national surveys, about 42 percent of U.S. women have obesity and an additional 27 ...
Mammary glands do not contain muscle tissue. The shape of female breasts is affected by age, genetic factors, and body weight. Women's breasts tend to grow larger after menopause, due to increase in fatty deposits caused by decreasing levels of estrogen. The loss of elasticity from connective tissue associated with menopause also causes sagging.
[66] [67] Female physical experiences vary depending on external forces such as diet, marriage patterns, culture, and other aspects. In Western nations menstruation begins to affect females at 13 and menopause starts around 51. In non-industrialized countries, on the other hand, most females begin menstruation at a later age. [68]
Hormones are involved in regulating body weight and the ability to achieve weight loss. Especially for women, they fluctuate throughout your menstrual cycle and during various life stages, like ...
In genetics, a maternal effect occurs when the phenotype of an organism is determined by the genotype of its mother. [1] For example, if a mutation is maternal effect recessive, then a female homozygous for the mutation may appear phenotypically normal, however her offspring will show the mutant phenotype, even if they are heterozygous for the mutation.
These genetic errors can affect the mind as well as the body and can result in schizophrenia, [14] [15] autism, [11] bi-polar disorder, [16] and cognitive [17] disabilities.

In medicine, genetic susceptibility to a disease refers to a genetic predisposition to a health problem, [1] which may eventually be triggered by particular environmental or lifestyle factors, such as tobacco smoking or diet. Genetic testing is able to identify individuals who are genetically predisposed to certain diseases.
