What causes varation in traits?

Genotypic variation is caused by mutation. Phenotypic variation can be caused by mutation, which gives rise to different alleles, or it can be caused by environmental factors.


A bell shaped curve of phenotypic variation is a representation of?

A bell shaped curve of phenotypic variation is a graphical representation of the distribution of a trait within a population. It shows that most individuals in the population have an average value for the trait, with fewer individuals on the extreme ends of the spectrum.


Which cross would produce the least phenotypic variation?

There are two choices that produce the least phenotypic variation. AA times aa produces only Aa offspring. AA times Aa produces and AA and Aa offspring.


What are the two types of variation shown by living organisms?

The two types of variation shown by living organisms are genetic variation, which is differences in DNA sequences among individuals, and phenotypic variation, which refers to observable traits or characteristics that vary among individuals.


What causes the variation in pitch?

it is caused when the variation is hit on the guitar


What is the root cause for variance of phenotype within a population?

The root cause of phenotypic variance within a population is genetic variation, which arises from differences in alleles among individuals. This genetic diversity is influenced by mutations, gene flow, and sexual reproduction, leading to a range of traits. Additionally, environmental factors, such as nutrition, climate, and social interactions, can further modify phenotypic expression, contributing to the overall variation observed in a population. Together, these genetic and environmental influences shape the phenotypic diversity seen in natural populations.


Brown eyes blue eyes and green eyes are an example of?

These eye colors are phenotypic expression of genotypes for eye color.


Difference between broad sense heritability and narrow sense heritability?

Broad sense heritability A.K.A (H) is the degree in which phenotypic variation is due to genetic factors Narrow sense heritability A.K.A (h) is the degree in which phenotypic variation is due to additive genetic factors. in maths terms... H = Vg/Vt h = Va/Vt Vg= genetic varaition Vt = total variation Va = additive variation


What causes variation of traits in a population?

the enviroment.


What kind of variation must exist in a population that has a wide range of phenotypes?

Genetic variation must exist within the population, meaning individuals have different alleles. This genetic diversity results in a wide range of phenotypes that can be observed. Environmental factors can also contribute to phenotypic variation within the population.


What is the term that means a variation of traits?

The term that means a variation of traits is "phenotypic variation." This refers to the observable differences in physical and physiological traits among individuals in a population, which can be influenced by genetic factors and environmental conditions. Variations can include differences in height, color, and behavior, and are crucial for the processes of natural selection and evolution.


How to calculate narrow sense heritability in a population?

To calculate narrow sense heritability in a population, you can use the formula: h (Vg / Vp), where h is the narrow sense heritability, Vg is the genetic variance, and Vp is the total phenotypic variance. This calculation helps estimate the proportion of phenotypic variation that is due to genetic factors.
