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.

What do you think the odds were that two children would turn out exactly alike

Anna007 [38]

No 2 people in the world are "exactly alike", so the odds would be 0% chance. Twins, might be closer in alike-ness, but they still aren't "exactly alike". Hope this answered your question.

Elden [556K]

Answer:

Codeine

Explanation:

Codeine is an opiate and is used to treat mild and moderate pain. It is also the main ingredient in prescription based cough suppressant. It belongs to a class of drugs known as opioid analgesics.

Codeine is a naturally occurring phenanthrene alkaloid with opioid agonist and can be extracted directly from the plant although most codeine is synthesized from the opium poppy.

This energy flows through organisms and the environment and eventually flows out of the biosphere as

kakasveta [241]

Heat is then the by-product of the light energy from the Sun flowing through the biosphere. Organisms are inevitably dependent on sunlight to perform essential biological processes in order to sustain life. In the absence of this energy, all the organisms on Earth would die.
