Well, DNA contains the hereditary information in the form of sequences of nucleotides which categorize as genes, that provide the information for synthesis of structural, functional and various other proteins that in combination and or in other ways determine an organism's complex traits. The phenotype of the said organism.

Answer: 1. S = 0.77
2. R = 0.14
Explanation:
1. <u><em>Selection</em></u> <u><em>differential</em></u> 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. <em><u>Response</u></em> <em><u>to</u></em> <em><u>Selection</u></em> 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. <em><u>Heritability</u></em> 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


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.
Causes:
1. the increase in population and growth of the human race
2. the need for housing and industrial advancements
effects:
1. loss of habitat for wildlife
2 loss of trees for oxygen
