Why is it more difficult to estimate heritability in humans than in livestock or laboratory animals?
Heritability is the likelihood of different traits being passed down in a species. It is more difficult to estimate in humans than in livestock or laboratory animals because humans are less controlled. Humans will interbreed among races and cultures, while animals generally keep to their own type.

About how many animals live in the US?
well there are a-lot of animals everywhere you go, but in the U.S. i would have to say about 60-75 million but that's including wild life. remember this was just a guess, so i am not positively sure.
How many sloths are there in the world today?
It is difficult to accurately estimate the global sloth population. However, researchers believe there are around 4,000 to 4,800 sloths in the wild.
What is the population of sloths?
It is difficult to estimate the exact population of sloths in the wild, but it is thought to be in the hundreds of thousands. Sloth populations are threatened by habitat loss, deforestation, and human activities.
How many lions existed in Africa the the 1950s?
It is difficult to estimate the exact number of lions in Africa in the 1950s, but it is believed that there were around 200,000 lions at that time. However, due to habitat loss, poaching, and human-wildlife conflict, the lion population has significantly declined since then.
How many mice are there in China?
It's difficult to provide an exact number since wild animal populations can fluctuate and are difficult to estimate accurately. However, China is estimated to have hundreds of millions of mice in various habitats across the country.

In order to estimate trait heritability researchers are most likely to make use of?
twin studies
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.
Is a statistical estimate of the proportion of the total variance in some trait that is attributable to genetic differences among individuals within a group.?
Heritability
How do you estimate the heritability of a certain trait?
Heritability of a trait is estimated using statistical methods, typically through twin, family, or adoption studies. Researchers compare the phenotypic variance of the trait within related individuals to that of unrelated individuals, often calculating heritability as the proportion of total variance attributable to genetic factors. Techniques such as regression analysis and genome-wide association studies (GWAS) may also be employed to refine estimates by linking genetic markers to trait variation. The resulting heritability estimate indicates the extent to which genetic differences contribute to observed differences in the trait within a specific population.
Heritability refers to the extent to which?
Heritability refers to the extent to which differences in a trait or characteristic within a population can be attributed to genetic differences. It provides an estimate of the proportion of individual differences in a trait that can be explained by genetic factors.
What is the heritability estimate for schizophrenia in the general population?
The heritability estimate for schizophrenia in the general population is typically reported to be between 60% and 80%. This indicates that a significant portion of the risk for developing schizophrenia is attributable to genetic factors. However, environmental influences also play a crucial role, highlighting that the disorder results from a complex interplay between genetics and environmental factors.
What is a statistical estimate of the proportion of the total variance in some trait that is attributable to genetic differences among individuals within a group?
Heritability is the statistical estimate of the proportion of the total variance in a trait that is attributed to genetic differences among individuals within a group. It provides a way to quantify the extent to which genetic factors contribute to individual differences in a specific trait within a population.
What do researchers mean when they talk about the heretibility of traits?
Heritability refers to the proportion of variation in a trait among individuals in a population that can be attributed to genetic differences. It is a statistical estimate that ranges from 0 to 1, where a heritability of 0 indicates that genetics do not contribute to trait variation, while a heritability of 1 suggests that genetics explain all the variation. Importantly, heritability is specific to a particular population and environment, meaning it doesn't apply universally across different contexts. Researchers use this concept to understand the genetic influence on traits such as height, intelligence, and susceptibility to certain diseases.
How do you estimate the narrow sense heritability based on the halfsib offspring of open pollinated trees?
First we need to calculate within and between family variance components for half sib families. Additive variance is equal to 4 time the additive variance and Dominance variance equal to within family variance - (3/4) additive variance.
Disadvantage of freehand cutting?
It is difficult to estimate or determine the exact quantity of fabric needed.
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.
