A breeder is trying to decrease the maturation time in a population of sunflowers. In this population, the mean time to flowerin
aalyn [17]

Answer:

The next generation average time to flowering will be 98 days.

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 = Xs - X₀

  • Heritability in the narrow-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 or lost 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.

<u>Available data:  </u>

  • trying to decrease the maturation time in a population of sunflowers.
  • the population mean time to flower is 100 days → X₀
  • Chosen parental Plants mean flowering time is 90 days → Xs
  • the narrow-sense heritability for flowering time is 0.2 → h²

According to what we sow previously, we need to find out the value of X₁, which reflects the next generation average time to flowering.

  • We know that R = X₁ - X₀, so we need to clear this formula to calculate X₁

X₁ = R + X₀

We already know that X₀ = 100 days,  

Now we need to calculate R.  

  • R = h²SD

We know that h² = 0.2,  

Now we need to calculate SD

  • SD = Xs - X₀

Xs = 90 days → Parentals media flowering time

X₀ = 100 → Population media flowering time

SD = Xs - X₀  

SD = 90 - 100  

SD = - 10 days

Knowing this, we can calculate R

  • R = h²SD

o h² = 0.2  

o SD = - 10

R = 0.2 x (-10)

R = - 2

  • Finally, once we know the R-value we can calculate the X₁ value

X₁ = R + X₀

X₁ = - 2 + 100

X₁ = 98

A. Review What are the major elements of life?
tino4ka555 [31]

Answer:

1. The major elements of life are Carbon, Hydrogen, Oxygen, Nitrogen, Phosphorus and Sulfur.

2. Its ability to catenate; its ability to form bonds easily with other elements such as hydrogen, oxygen and nitrogen; its ability to form single, double and triple.

3. Carbohydrates, Proteins, Lipids, and Nucleic acids

4. Carbohydrate provide energy; Proteins serve as structural elements;

Lipids serve as structural components of membranes;

Nucleic acids store and transmit genetic information

5. Proteins are considered polymers while Lipids are not because proteins are composed of monomeric subunits of amino acids whereas lipids do not have monomeric subunits.

Explanation:

1. The major elements of life are Carbon, Hydrogen, Oxygen, Nitrogen, Phosphorus and Sulfur as they are found in many structures of living organisms- in proteins, carbohydrates, nucleic acids and lipids.

2. Carbon has the ability to form different large and complex structures because:

(I) its ability to catenate which is the ability to combine with one another to form straight, branched chain or ring compounds containing many carbon atoms.

(ii) carbon can form single, double and triple with itself and other life elements.

(iii) the relative stability of the covalent bonds formed by carbon.

3. Four groups of organic compounds found in living things are Carbohydrates, Proteins, Lipids, and Nucleic acids.

4. Carbohydrate provide energy; Proteins serve as structural elements;

Lipids serve as structural components of membranes;

Nucleic acids store and transmit genetic information

5. Polymers are large molecular weight compounds built up from subunits called monomers.

Proteins are considered polymers because they are large molecular weight molecules composed of monomeric subunits of amino acids.

Lipids are not considered polymers because individually, they are not very large molecules and do not have monomeric subunits rather are composed of long fatty acids chains linked to a glycerol molecule.
