Explain how diversity within a population influences the heritability of a particular trait.
Heritability is the extent to which differences in the appearance of a trait across several people can be accounted for by differences in their genes. So this suggests that if the group is diverse, there will be people from multiple arenas who come up to us to try an get involved. We will have so many options to explore and also many ways to get better. There will also be a way out to get connected with people form so many ranges of culture and backgrounds. The idea should only be this that we try to connect with them at all levels. Hence it will give a way and path to heritability.
Explain how diversity within a population influences the heritability of a particular trait.
If heritability of a trait in a population of tomatoes is 0.6, and the present population mean for sugar content is 5%, what would be the estimated mean of the next generation if it originates from a selected population whose sugar content is 10%?
Assume that you have a population in Hardy-Weinberg equilibrium for a particular trait Within this population, what will be the proportion of matings between homozygotes?
How would you combine adoption and twin study techniques to determine the heritability of a trait?
What is meant by the term heritability? 1. Heritability refers to the degree to which observed phenotypic variation for a given trait is inherited. 2. Heritability is the process of choosing specific individuals with preferred phenotypes from an initially heterogeneous population for future breeding purposes. 3. Heritability refers to a quantitative range generated at fertilization within which a particular individual can fall. 4. Heritability is a continuous variation across a range of phenotypes in generations. What functional information about a...
You determine broad-sense heritability for quantitative trait and find a very low H^2 value. This could be caused by: Question options: a). Having a huge number of loci controlling the trait, with variants in each locus having very little (quantitative) contribution to that trait. b). Genotypic variation having a major effect on gene-gene interactions c). Having a significant level of narrow-sense heritability, which is not represented within the broad-sense Heritability d) The increased difficulty in detecting broad-sense heritability for continuous...
a. Why is heritability necessary for natural selection? How would you expect a trait for which there is no resemblance between parents and offspring to change over time? b. Why is differential success among organisms with different variants of a trait necessary for natural selection? How would you expect a trait for which there is no differential success to change over time?
In a population of fruit flies, 37.5% possess a particular trait, T. Suppose 25% of the females possess the trait, and that the population is composed of equal numbers of males and females. If a fruit fly is selected at random from the population, and it possesses the trait T, what is the probability that it is female?
Genetic Traits and genetic disorders are influenced in one way or another by the environment. On the other hand, the heritability of a disorder examines the variations in multifactorial traits due to genetics in a particular population and focuses on the genetic component of variations seen in a trait. Select a genetic disorder caused by a single-gene trait that is multifactorial. Explain how your chosen genetic disorder is influenced by the environment. Select two diseases—one with high heritability and one...
Why is it impossible to understand the differences in traits between groups by measuring narrow-sense heritability of those traits within the groups? What is the difference between saying there is no genetic basis for a trait and saying that all of the phenotypic variation in a trait for a given population can be explained by variation in environment?
