After an exceptionally rainy spring, there is no longer a barrier between the populations, and some individuals migrate inland f

Naddika [18.5K]

Answer

After inland population after migration allele frequency is 0.62 or 62%

Explanation:

Given,

Coastal striped phenotype freq. = 0.22

ss = 0.22

$q_{coastal} \times q_{coastal} = 0.22$

$q_{2 coastal}$ = 0.22

Similarly, inland striped phenotype freq. = 0.43

$q_{2inland}$ = 0.43

$q_{coastal} = \sqrt{q_{2coastal}}$

= $\sqrt{0.22}$

= 0.4690

$q_{coastal}$ = 0.47 i.e. 47%

$q_{inland} = \sqrt{0.43}$

= 0.655

$q_{inland}$ = 0.66 i.e. 66%

the migration range (m) is given as 20%

m= 0.2

allele freq. after migration = pre migration + ∆q

here,

∆q = change in the allele frequency

migration of allele freq. from coastal to inland

= $m(q_{coastal} - q_{inland})$

= 0.2 (0.47 – 0.66)

= $0.2 \times (- 0.191)$

= - 0.0382

∆q = -0.04 i.e. 4%

Georgia [21]

For a pre-event meal, rich sources of carbohydrates, such as bagels, muffins, and bread, should be eaten two to four hours before an endurance event. Eating a calorie dense meal 2 to 4 hours before an endurance event or smaller meals between 2 to 5 hours before, is absolutely essential for topping of muscle glycogen levels as well as providing blood glucose for the intense activity ahead.

Deffense [45]

The manipulation of genes for practical purposes, such as medicine, agriculture, or criminal justice, is called GENETIC ENGINEERING. These technologies involve the manipulation of the DNA molecule.

Deoxyribonucleic acid (DNA) is the molecule that carries the instructions (i.e., genes) for all organisms to develop, survive, grow and reproduce.

Genetic engineering techniques consist of the manipulation of the DNA molecule in order to produce desirable phenotypic features in the offspring of an organism.

Genetic engineering techniques use recombinant DNA strategies to modify the genetic makeup (DNA) of the target organism.
