What effect does each type of selection have on the mean of the trait in the next generation?
Directional:
Stabilizing:
Disruptive:
Homework Answers
Directional result if the election favours small and large sized individual more individual of that type will be present in next generation with continued selection over the generation mean size of population would have changed
stabilizing if selection favours average size the number of small and large sized individual will decline and the trait of average size will remain predominant it is stabilizing which reduces variation and maintain mean value.
directional when natural selection favour both small sized and large sized indiidual natural selection will be disruptive . It produce two peak in distribution of trait that may lead to development of two population.

Each of the graphs represents the distribution of a quantitative, heritable trait. In each example, selection occurs that alters the position or shape of the normal distribution.

Part B - How does this research relate to your biology course? The following graph shows the frequency distribution of a heritable trait -- fur color -- in a hypothetical deer mouse population. The x-axis represents variation in fur color from light to dark. The y-axis represents the percentage of individuals in the population with each particular color of fur. 333 There are three ways in which natural selection can alter the frequency distribution of a heritable trait, such as...

Directional selection Stabilizing selection Disruptive selection Individuals of a bat species have wingspans ranging from 20 cm to 40 cm. After several generations, most bats have either small wingspans or large wingspans. Individuals of a bird species lay between 1 and 20 eggs. Individuals of the bird species lay between 5 and 15 eggs after several generations. Individuals of...

One selective force (or mixture of forces) limits the largest viable birth weight of a human baby, while another selective force limits the smallest viable birth weight of a baby. This is called .............. natural selection. a. Artificial b. Fictional c. Directional d. Disruptive e. Stabilizing A population splits into two rather different populations. The two phenotypic extremes of the original population are favored over the more common central phenotype of the original population. This is called ............ natural selection....
