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 decides a trait?
A trait is determined by a combination of genetic factors and environmental influences. Genes code for specific traits, but the expression of those genes can be influenced by the environment in which an individual lives. This interplay between genetics and the environment ultimately shapes an individual's traits.
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.
How can environmental factors impact the development of a specific trait, and can you provide an example of how this influence occurs in nature?
Environmental factors can impact the development of a specific trait by influencing gene expression or altering the physical environment in which an organism grows. For example, the color of a butterfly's wings can be influenced by the temperature during its development. Warmer temperatures can lead to darker wing colors, while cooler temperatures can result in lighter colors.
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.
What is a multifactorial trait?
Trait that is controlled by many genes and is also influenced by the environment.
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.
Example of a sexually influenced trait?
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.
Why are the identical twins different?
Because genes do not account for every trait or characteristic. Some characteristics are influenced by environment.
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 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 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.
What is an adaptation trait?
An adaptive trait is one that helps an individual better interact with their environment. Adaptive traits include thumbs in humans for example.

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.
