How does the type of rock in Earth's crust affect the distribution of groundwater
Ilia_Sergeevich [38]

Answer:

Obviously, such rocks transmit only small quantities of water and are poor aquifers. By comparison, rocks such as fractured sandstones and cavernous limestone have large connected openings that permit water to move more freely; such rocks transmit larger quantities of water and are good aquifers.

let A and a represent dominant and recessive alleles whos respective frequencies are p and q in a given interbreeding population
lesantik [10]

Answer:

A) 48 %

B) 18 %

Explanation:

A) Given

Frequency of individuals in the population having recessive phenotypes = 16%

Frequency of individuals in the population having recessive phenotypes is represented by q^2

q^ 2 = 0.16\\q= \sqrt{0.16}\\ q = 0.4

Thus frequency of recessive genes is equal to 40%

frequency of dominant genes is equal to

p = 1-q\\= 1-0.4\\= 0.6

Now,

p^2 + q^2+2pq = 1\\2pq = 1-0.16-0.36\\2pq = 0.48

48 % of genes exist in the heterozygous condition

B.

Frequency of individuals in the population having recessive phenotypes = 1%

Frequency of individuals in the population having recessive phenotypes is represented by q^2

q^ 2 = 0.01\\q= \sqrt{0.01}\\ q = 0.1

Thus frequency of recessive genes is equal to 10%

frequency of dominant genes is equal to

p = 1-q\\= 1-0.1\\= 0.9

Now,

p^2 + q^2+2pq = 1\\2pq = 1-0.01-0.81\\2pq = 0.18

18 % of genes exist in the heterozygous condition
