The answer is <span>A. p2 = 0.36, 2pq = 0.48, q2 = 0.16.

Let's first distinguish alleles frequencies from genotypes frequencies:
p - a frequency of R allele,
q - a frequency of r allele,
p² - a frequency of RR genotype,
2pq - a frequency of Rr genotype,
q² - a frequency of rr genotype.
<span>The gene frequency of allele r changes from 0.38 to 0.40, thus:
</span>q = 0.40
Now, we will implement this in the following equation:
p + q = 1
If q = 0.40, then:
p + 0.40 = 1
⇒ p = 1 - 0.40
⇒ p = 0.60
Now, the frequencies of both alleles are know and it is easy to calculate the <span>genotype frequencies:
-</span> the frequency of RR genotype: p² = 0.60² = 0.36
- the frequency of Rr genotype: 2pq = 2 · 0.60 · 0.40 = 0.48
- the frequency of rr genotype: q² = 0.40² = 0.16
Therefore, the new genotype frequencies in that population are <span>p2 = 0.36, 2pq = 0.48, q2 = 0.16.</span>
Chemotrophs (Bacteria) are essential in the conversion of nitrogen containing compounds to nitrogen forms that are accessible and usable by plants.
The statement: Fertilization usually takes place in the fallopian tube is True
The fallopian tube links the ovary to the womb/uterus. So therefore, the fertilization of an egg by a sperm occurs in the fallopian tube
- As many as 50 percent of zygotes do not survive the first two weeks is also True
The zygote is formed as a result of the fusion between sperm and egg
During the period of the fetus, the most rapid prenatal changes take place. True
<h3>What is fertilization? </h3>
This the process which occurs as a result be of the union of sperm and egg which fuses to form zygote

Answer: The symbiotic nitrogen-fixing bacteria invade the root hairs of host plants, where they multiply and stimulate formation of root nodules, enlargements of plant cells and bacteria in intimate association. Within the nodules the bacteria convert free nitrogen to ammonia, which the host plant utilizes for its development. brainliest?
