Can obesity in mothers lead to autism in children?
No, obesity in mothers cannot lead to autism in children. Although we don't know the exact causes of autism it is largely due to genetic factors and genetic mutation, there is some evidence to link certain environmental factors such as use of certain antidepressants with autism but it's not conclusive. There is nothing to suggest obesity in the mother would lead to autism in her child.
What are the causes of fabroid?
Fibroids are benign tumors that can develop in the uterus due to hormonal imbalances, genetic factors, and estrogen levels. They can also be influenced by factors like age, obesity, and family history. The exact cause of fibroids is not fully understood.
How many percent girls have Adams apple?
Typically, less than 1 percent of girls have a visible Adam's apple due to hormonal and genetic factors. It is more common in males due to differences in the size and shape of the larynx during puberty.
Who did research on osteoarthritis due to obesity?

Is Alzheimers Disease genetic?
Approximately 10-15% of dementias of the Alzheimer's type are believed to be genetic in origin. The remainder are postulated to be due to environmental factors.
Can DNA be wrong when determining a person's genetic traits?
Yes, DNA can sometimes be inaccurate in determining a person's genetic traits due to factors such as mutations, genetic variations, and environmental influences.
Are cases of polydactyly always genetic?
Cases of polydactyly can be either genetic or occur sporadically. Genetic polydactyly is inherited and can be passed down in families, while sporadic polydactyly may result from random genetic mutations or other factors.
What of these statements is true populations are constantly evolving?
Yes, populations are constantly evolving due to factors such as genetic mutations, natural selection, genetic drift, and gene flow. This leads to changes in the genetic makeup of a population over time.
What is the leading cause of obesity in kids today?
The leading cause of obesity in kids today is a combination of factors, including excessive consumption of high-calorie, low-nutrient foods, lack of physical activity, genetics, and environmental factors such as family dynamics and socioeconomic status. Additionally, factors like increased screen time and marketing of unhealthy foods to children also contribute to the rise in childhood obesity.
What factors contribute to babies being born with gray hair, and is it a cause for concern or simply a genetic trait?
Babies born with gray hair may be due to genetic factors, such as a lack of melanin production or a genetic mutation. It is usually not a cause for concern and may simply be a genetic trait. However, it is important to consult a healthcare provider for a proper evaluation and guidance.
What is the narrow sense heritability equation and how is it used to quantify the genetic contribution to a specific trait in a population?
The narrow sense heritability equation is a statistical formula used to estimate the proportion of variation in a trait that is due to genetic factors. It is calculated by dividing the additive genetic variance by the total phenotypic variance. This equation helps quantify the genetic contribution to a specific trait in a population by providing a numerical value that represents the extent to which genetic factors influence the trait compared to environmental factors.
Growth occurs due to what?
Growth occurs due to an increase in the number and size of cells in an organism. This process is regulated by various growth factors, hormones, and genetic factors that control cell division and differentiation. Environmental factors such as nutrition, exercise, and stress can also influence growth.
