One example of a sexually influenced trait in humans would be haemophilia. The gene responsible for haemophilia is located on the X chromosome, and if a man receives a gene from his mother (men's X chromosomes always come from their mother) that is positive for this trait, he will exhibit haemophilia. Women must have two X chromosomes that are positive for haemophilia in order to exhibit the trait, because it is a recessive gene.

What is an example of epigenetic trait?
An example of an epigenetic trait is the inheritance of coat color in mice. This trait can be influenced by epigenetic modifications such as DNA methylation, which can be passed down from one generation to the next without changes to the underlying DNA sequence.
What is a trait that is overridden by another trait?
Eye color is an example of a trait that is typically determined by genetic inheritance, but can also be temporarily influenced by wearing colored contact lenses. This demonstrates how environmental factors can override genetic traits.
What is continuously varying trait?
A discontinuous trait is the opposite of a continuous trait. They are "either/or" traits that do not have any range. An example would be the sex of an offspring, whereas an example of a continuous trait would be haircolor, where many options are available.
What is the condition called when there are many genes that affect a trait which are susceptible to changes due to the environmental factors?
This condition is known as polygenic inheritance. It involves multiple genes contributing to a trait, and the expression of these genes can be influenced by environmental factors. The combination of genetic and environmental influences leads to a wide range of variation in the trait.
What influenced Gordon Allport trait theory?
Gordon Allport's trait theory was influenced by his study of personality and his belief that traits could be used to categorize and describe individual differences. He was also influenced by the work of Sigmund Freud and Carl Jung, as well as by his own clinical observations of personality. Additionally, Allport was influenced by his dissatisfaction with earlier trait theories that he felt were too broad and lacking in specificity.
What are the example of sex influenced traits and with definition?
An example of a sex-influenced trait is male pattern baldness, where the expression of the trait is influenced by sex hormones. In males, high levels of dihydrotestosterone can lead to hair loss, while females with the same genetic predisposition are less likely to be affected. This trait is influenced by sex hormones but not exclusively linked to a specific sex.
What is an example of epigenetic trait?
An example of an epigenetic trait is the inheritance of coat color in mice. This trait can be influenced by epigenetic modifications such as DNA methylation, which can be passed down from one generation to the next without changes to the underlying DNA sequence.
What genetic traits are sex-influenced?
Sex-influenced traits are those where the same genotype results in different phenotypes in the sexes. One example of a sex-influenced trait is pattern baldness. If a male is heterozygous for this trait, he would most likely go bald. However, if a female was heterozygous for this trait, she would probably not go bald.
Is diabetes an example of a dominant or recessive trait in genetic inheritance?
Diabetes is not a simple genetic trait like dominant or recessive. It is a complex condition influenced by multiple genes and environmental factors.
An example of a trait influenced by the environment?
Sun exposure affecting skin color is an example of a trait influenced by the environment. People living in sunnier regions tend to have darker skin compared to those in less sunny areas due to the production of melanin in response to UV radiation.
What is a multifactorial trait?
Trait that is controlled by many genes and is also influenced by the environment.
What is a trait that is overridden by another trait?
Eye color is an example of a trait that is typically determined by genetic inheritance, but can also be temporarily influenced by wearing colored contact lenses. This demonstrates how environmental factors can override genetic traits.
What is continuously varying trait?

Is eye color an example of a trait?
False, eye color is an example of a trait. Hair color, nose shape, and curly and not curly hair are all also traits. Anything that can possibly be unique and distinguishable is a trait, so yes, eye color is a trait.
Why is height considered a polygenic trait?
Height in considered a polygenic trait because your height is influenced by multiple genes.
Is height in humans is an example of a single gene traits?
Height in humans is not an example of a single gene trait. It is a polygenic trait, meaning it is influenced by multiple genes as well as environmental factors. Multiple genes interact to determine an individual's height, making it a more complex trait.
What is the condition called when there are many genes that affect a trait which are susceptible to changes due to the environmental factors?
This condition is known as polygenic inheritance. It involves multiple genes contributing to a trait, and the expression of these genes can be influenced by environmental factors. The combination of genetic and environmental influences leads to a wide range of variation in the trait.
