The recessive allele frequency decreased (q = 0.14) and the dominant one increased (p = 0.86). Genotypic frequencies followed this tendency too (q² =0.02, 2pq = 0.24 and p² = 0.74). The Carbonaria phenotype increased to 0.98, while Typica showed a frequency of 0.02.
------------------------------------------
Available data:
Some moths were released in the forest (N=1000). 250 were white, and 750 were black.
The color is defined by a single diallelic gene. The dominant allele -D- codes for black color (carbonaria), while the recessive allele -d- codes for white (Typica).
These individuals produced five new generations since they were released, G1, G2, G3, G4, G5.

This information is guiding you to know how to calculate frequencies and total numbers. Information about released individuals is an example of how you need to proceed.
Firts, we will assume that this population is under Hardy-Weinberg equilibrium. So let us review some theoretical framework.
The allelic frequencies in a locus ⇒ p and q ⇒ dominant and
recessive alleles.
The genotypic frequencies after one generation are p² (H0m0zyg0us dominant), 2pq (Heterozyg0us), q² (H0m0zyg0us recessive).
If a populations is in H-W equilibrium, it will get the same allelic frequencies generation after generation.
The sum of allelic frequencies equals 1 ⇒ p + q = 1. The sum of genotypic frequencies equals 1 ⇒ p² + 2pq + q² = 1Now let us analyze the problem.
We need to get information on G5 generation. We will do it step by step.
1) Phenotype frequencies
To get the Phenotype frequencies, we just need to divide the number of individuals with each phenotype by the total number of individuals in this generation. So,
Total number of individuals in G5 → 1435 White = Typica = 29 individuals Black = Carbonaria = 1406 individuals
⇒ F(Typica) = 29 / 1435 = 0.02
⇒ F(Carbonaria) = 1406 / 1435 = 0.979 ≅ 0.98
2) Allelic Frequencies
We can use the phenotypic frequencies to get the allelic frequencies.
Remember that carbonaria (black) moths include h0m0zyg0us dominant (DD) and heter0zyg0us (Dd) individuals. So we can not get the allelic frequencies from this data.
We can only use the allelic frequency of Typica (White) individuals. Typica phenotypic frequency only includes h0m0zyg0us recessive individuals, dd.
We know that,
H0m0zyg0us recessive genotype → dd
Genotypic frequency → F(dd) → Represented as q²
F(Typica) = F(dd) = q² = 0.02
Recessive allele → d
Recessive allelic frequency → f(d) → Represented as q
f(d) = q = ??
q² = 0.02
q = √ 0.02
q = 0.1414 ≅ 0.14
0.14 is the recessive allelic frequency. Now we should calculate the dominant allelic frequency. To do this, we will clear the following formula,
p + q = 1
p + 0.14 = 1
p = 1 - 0.14
p = 0.86
So, now we also know that
⇒ f(D) = p = 0.86
⇒ f(d) = q = 0.14
3) Genotypic Frequencies
Now, we need to get the genotypic frequencies, F(xx)
⇒ F(DD) = p² = 0.86² = 0.7396 ≅ 0.74
⇒ F(Dd) = 2pq = 2 x 0.86 x 0.14 = 0.24
⇒ F(dd) = q² = 0.14² = 0.0196 ≅ 0.02
4) Number of individuals
Finally, we need to tell the number of individuals with each genotype. We just need to multiply each frequency by the total number of individuals in G5.
F(DD) = p² = 0.74
F(Dd) = 2pq = 0.24
F(dd) = q² = 0.02
Total number of individuals = 1435
⇒ DD Black -Carbonaria- individuals → 0.74 x 1435 = 1,061.9 ≅ 1062
⇒ Dd Black -Carbonaria- individuals → 0.24 x 1435 = 344.4 ≅ 344
⇒ dd White -Typica- individuals → 0.02 x 1435 = 28.7 ≅ 29
From this results, we can conclude that the moths population is not in H-W equilibrium, because their allelic and genotypic frequencies changed through generations.
It seems that Natural selection is favoring the dominant phenotype by increasing the frequency of the dominant allele over the recessive one. Probably directional selection is acting on this population.

19. Each beaker shown below contains an amphibian egg collected from one of four different
Which of these beakers contains an egg that would shrink?
3
2
4
1
Answers
Since water is more concentrated in the egg's interior of beaker 3 than the exterior, this egg will shrink. Water will move, by osmosis, from inside the egg to the exterior. The correct option is a) Beaker number 3.
In any of these situations, water will move through osmosis, if it moves.
What is osmosis?Osmosis is the water molecules transport by simple diffusion through the semipermeable membrane, following a concentration gradient.
Water molecules can freely move through momentary openings in the membrane that are formed as a result of lipids movements.
Osmosis is the phenomenon that occurs when two dilutions of different concentrations -for instance, the interior of the cell and another solution- are separated by a semipermeable membrane.
Since water moves according to its concentration gradient, we need to consider in which side of the membrane water is more concentrated.
The egg will shrink only if it loses water. And it will lose water if it is more concentrated in the interior of the egg than in the exterior.
Beaker Water concentration Water movement
inside the egg outside the egg
1 93% 93% No movement
2 80% 91% To the interior
3 99% 92% To the exterior
4 90% 95% To the interior
In beaker 3, water is more concentrated in the egg's interior than the exterior. This egg will shrink because water will move from inside the egg to the exterior.
The correct option is a) Beaker number 3.
