A genetically heterogeneous population of rice has a mean in the number of days to maturation of 30. Selection for decreased per

chubhunter [2.5K]

Answer:

h² = 0.6

Explanation:

Before answering the question, we need to know a few concepts.

Artificial selection is the selecting practice of a specific group of organisms in a population -that carry the traits of interest- to be the parents of the following generations.

Parental individuals carrying phenotypic values of interest are selected from the whole population. These parents interbreed, and a new generation is produced.

The selection differential, SD, is the difference between the mean value of the trait in the population (X₀) and the mean value of the parents, (Xs). So,

SD = X₀ - Xs

Heritability in the strict sense, h², is the genetic component measure to which additive genetic variance contributes. The heritability might be used to determine how the population will respond to the selection done, R.

h² = R/SD

The response to selection (R) refers to the metric value gained from the cross between the selected parents. R can be calculated by multiplying the heritability h², with the selection differential, SD.

R = h²SD

R also equals the difference between the new generation phenotypic value (X₁) and the original population phenotypic value (X₀),

R = X₀ - X₁

-------------------------------------------------------------------------------------------------------------

Now that we know these concepts and how to calculate them, we can solve the proposed problem.

Available data:

You are selecting rice´s decreased period of maturation.
The population of rice has a mean maturation time of 30 days → X₀
Parental selected average period to maturation is 25 days → Xs
F1 plants mature on average in 27 days → X₁
N arrow sense Heritability → h²

According to what we sow previously, we need to find out the value of h².

We know that h² = R/SD, so we need to get R and SD first.

R = X₁ - X₀

R = 27 - 30

R = -3

SD = Xs - X₀

SD = 25 - 30

SD = -5

Knowing this, we can calculate h²

h² = R/SD

h² = -3/-5

h² = 0.6

The fat that is stored in the abdominal region is classified as

Kipish [7]

Answer:

Visceral fat

Explanation:

Visceral fat is one of the types of body fat which is stored in the region of abdominal cavity. The visceral fat is located near several vital organs that are found in the visceral region. Such organs around which the visceral fat is located are liver, stomach and intestines. This fat sometimes also gets build up in the arteries. “Active fat” is a term which is often used for the visceral fat because it actively increases the risk of some serious health problems.

Why is it when your nose i plugged you cant taste things?

sashaice [31]

Answer and explanation:

That's because the upper part of your nose isn't open to receive the chemicals that trigger the olfactory receptors (those inform your brain and create the sensation of flavor).

Structure and function of cytoplasm

Andrei [34K]

Answer:

Cytoplasm is often referred as the fluid(s) that will enter and fill the cell. It includes cytosol, proteins, ions, filaments, and large molecules (macromolecular structures) with organelles that have been suspended into the cytosol. The function for the cell is to hold and provide a medium for the cellular contents!

I hope this helps you! This was based off my knowledge of the subject.
