Answer:
The frequency of blue eyes in population 2 after the migration is q₂´ = 0.195 ≅ 0.2
Explanation:
Whenever migration, m, occurs between two populations, there is genetic flow going on. Genetic flow is an evolutive strength only if migration > 0 and if the allelic frequency in one generation is different from the allelic frequency in the next generation.
Genetic flow acts homogenizing the allelic frequencies between the two populations, and it might introduce variability into the new one.
For genetic flow to be possible, there needs not only the movement of the genes from one population to the other but also the reproduction process on the new population. Hence, it involves an interaction between the dispersion pattern and the reproductive system.<u>

<u>Available data:</u>
- Population 1 → frequency of the recessive allele b = 0.3
- Population 2 → frequency of the recessive allele b = 0.15
- m = proportion of gametes coming from the population 1 = 30% = 0.3
- <em>1-m = proportion of gametes that remain in the population</em>
- <em>p = frequency of the dominant allele in population 1 before migration</em>
- <em>q = frequency of the recessive allele in population 1 before migration</em>
- <em>p´ = frequency of the dominant allele in population 2 after migration</em>
- <em>q´ = frequency of the recessive allele in population 2 after migration</em>
To calculate the frequencies of the gametes (p1, q1, p2, q2) after migration, we can use the following equations:
- p₁’ = p₁ (1 - m) + p₂ x m
- q₁´ = q₁ (1 - m) + q₂ x m
- p₂’ = p₂ (1-m) + p₁ x m
- q₂´ = q₂ (1 - m) + q₁ x m
So to know the frequency of blue eyes in population 2 after the migration, we just need to replace the terms in the equation for the given values, and then calculate q₂´.
q₂´ = q₂ (1 - m) + q₁ x m
q₂´ = 0.15 (1 - 0.03) + 0.3 x 0.3
q₂´ = 0.105 + 0.09
q₂´ = 0.195 ≅ 0.2
The hypothalamus is the gland which produce no hormones.
<h3>
What hypothalamus do?</h3>
The brain's hypothalamus is a section that lies immediately below the thalamus. Being the connecting link between the endocrine and neurological systems, despite its tiny size, this area is crucial for the healthy operation of the organism.
The hypothalamus does not secrete any hormones in this situation; instead, it controls hunger, thirst, blood pressure, and temperature.

B:Producer, A host is the species that has the disease/virus.
Angiosperms have flowers. The flowers are special structures for reproduction. They contain male parts that make pollen and female parts that contain ovules. Some plants have these male and female parts in different flowers.F
B the farther down you go the colder it gets because its harder for the sunlight to penetrate deeper water causing it to be darker and cooler
