1: What is the best way to compare the ages of layers from the two different locations?

pishuonlain [190]

Answer:

Explanation:

By using the radioactive dating to compare the ages of the rocks in different layers is the best way to compare the ages of layers from the two different areas as there is a sect in a rock formation, the oldest rocks are in the bottom layer and the most newborn rocks are in the top layer. Geologists have produced a set of principles to compare the ages of rock layers. They apply these principles to organize the layers according to their corresponding ages.

You are an almond grower and want to determine whether almond size (measured as shelled almond weight) is a heritable trait. A s

inn [45]

Answer: 1. S = 0.77

2. R = 0.14

Explanation:

1. Selection differential is the difference between the population mean and the average of the selected parents. Its symbol is S.

S = mean of selected parents - population mean

S = 6.48 - 5.71

S = 0.77

2. Response to Selection is how much gain you make when crossing over selected parents. Its symbol is R.

R = mean of offspring of selected parents - population mean

R = 5.85 - 5.71

R = 0.14

3. Heritability is, basically, a statistical variable that shows how much the variation in a trait is due to genetic factors. Its symbol is h².

To calculate it, use Breeder's Equation:

R = h²S

$h^{2}=\frac{R}{S}$

$h^{2}=\frac{0.14}{0.77}$

h² = 0.18

4. You would expect the production to be strongly influenced by environment, because heritability lies between 0 and 1. Low heritability means there is low level of resemblance between offspring and parents. As this program heritability is low, the resemblance is small, which means the characteristics are influenced mostly by the enviroment.
