Populations in H-W equilibrium have the same allelic and genotypic frequencies generation after generation. f(Sb) = p = 0.626. f(Sb+) = q = 0.374. F(SbSb+) = 2pq = 0.468
What is Hardy-Weinberg Equilibrium?
The Hardy-Weinberg equilibrium is a theory that states that, assuming a diallelic gene,
⇒ The allelic frequencies in a locus are represented as p and q.
• The frequency of the dominant allele p(X) is p
• The frequency of the recessive allele p(x) is q
⇒ The genotypic frequencies after one generation are
• p² (Homozygous dominant genotypic frequency),
• 2pq (Heterozygous genotypic frequency),
• q² (Homozygous recessive genotypic frequency).
Allelic and genotypic frequencies remain the same through generations in a population that is in H-W equilibrium.
The addition of the allelic frequencies equals 1
p + q = 1.
The sum of genotypic frequencies equals 1
p² + 2pq + q² = 1
In the exposed example,
Sb is dominantSb+ is recessive ⇒ wild typePopulation size ⇒ 137 + 836 = 973Individuals with wildtype bristles ⇒ 137 ⇒ Sb+Sb+Individuals with stubble bristles ⇒ 836 ⇒ SbSb and SbSb+First, we will get the frequencies.
To do it, we will use the number of individuals. These values will tell us about phenotypic frequencies,
Phenotypic frequency
F(wildtype) = q² = 137/973 = 0.14F(stubble) = p² + 2pq = 836/973 = 0.86Now, we will use the frequency of the recessive phenotype to get its genotypic and allelic frequencies.
F(Sb+Sb+) = q² = 137/973 = 0.14 ⇒ Recessive Genotypic frequency
f(Sb+) = q = √0.14 = 0.374 ⇒ Recessive Allelic frequency
Now, Since this population is in H-W equilibrium, we will use q (recessive allelic frequency) to get the dominant allelic frequency and the dominant genotypic frequency. To do it, we will clear the following equation,
p + q = 1
p + 0.374 = 1
p = 1 - 0.374
p = 0.626 ⇒ Dominant Allelic frequency
F( SbSb) = p² = 0.626² = 0.392 ⇒ Dominant Genotypic frequency
Finally, we will get the heterozygous frequency. There are two options,
To susbtract the dominant genotypic frequency to the dominant phenotpic frequency,F(SbSb + SbSb+) - F(SbSb) = 0.86 - 0.392 = 0.468
To clear the following equation,p² + 2pq + q² = 1
0.392 + 2pq + 0.14 = 1
2pq = 1 - 0.392 - 0.14
2pq = 0.468
Answers:
- f(Sb) = p = 0.626 ⇒ Dominant Allelic frequency
- f(Sb+) = q = 0.374 ⇒ Recessive Allelic frequency
- F(SbSb+) = 2pq = 0.468 ⇒ Heterozygous frequency

The correct answer is C. Gardeners choose which plants they let reproduced based on the plant traits.
Explanation:
In general, selective breeding involves the intervention of humans in the reproduction of species, this includes mainly plant and animal species. Moreover, in selective breeding, humans choose which specific species or individuals reproduce to favor certain traits. For example, a farmer might allow only the biggest cows to reproduce because this will lead to bigger calves. In this context, the option that shows selective breeding is C because this shows the intervention of humans in reproduction by selecting the individuals that will reproduce.

Explanation:
A family business had bred dogs for over 250 years. During this time, 125 generations of dogs were bred for a single trait: protective instincts. Immediately after
birth, the puppies are sorted based on whether or not they have a white patch of fur on their chests. Those without this trait, are no longer bred for their
business and instead are adopted to pet stores and not private sales for people requesting the desired trait of protective instincts.
How could the breeders know these other dogs will not have the traits they are looking for when they are just new-born puppies?
Answer:
They can know if the trait has been carried on by looking at the bred dogs that have the trait and determining if the trait has been passed down by similar characteristics between the parent with the trait and the puppy that could have the trait.
Explanation:
Gregor Mendel, a 19th century monk, used pea plants to arrive at several conclusions
about how traits are passed on to offspring. One conclusion became known as the Law of
Segregation. The illustration below shows how this law operates.
Parent 1
Parent 2
Offspring 1 Offspring 2 Offspring 3 Offspring 4
Which conclusion can you make based on Mendel's work as shown in the diagram?
Parent 1 has the dominant trait
Parent 2 has the dominant trait.
The offspring inherit traits only from Parent 1.
The offspring will not pass on the trait, inherited from Parent 2, to their offspring.

The illustration is a representation of multiple gene alleles on the same chromosome. One inherited trait linked to alleles "A", "a", "D", "D", "t", and "T" is determined by __________.
Answer:
A characteristic linked to the alleles that is inherited is the genotype.
Explanation:
The genotype is the genetic makeup of an individual. The genotype is determined by the alleles and is passed from father to son through the transmission of alleles, that is, the genotype is an inheritable characteristic. The genotype cannot be modified by the environment, nor can it be modified in a natural way, but it can be modified through mutations that are also inheritable.

C. feature detectors.
D. figure processors.
Answer:
C
Explanation:
Neurons that respond to certain types of lines are examples of feature detectors found in Option C. Neurons are the monomeric units of the nervous system that play an important role in transmission.
What is the importance of the neuron?
The neuron is a unit in which the message is transmitted from the neuron to another neuron, and this can be done by either chemical signaling or by electric signaling. The neuron receives sensory stimuli from the sensory organ and transmits them to the spinal cord.
Later, the message from the spinal cord is sent to the motor organs, and the whole pathway of the neuron signaling from the sensory to the motor organ is called the reflex arc. The neuron takes part in the signaling process so that the muscle can function, regulate the contraction relaxation, and perform many other functions.
Hence, neurons that respond to certain types of lines are examples of feature detectors found in Option C.

Answer:
B. The amounts of sun, water, and
nutrients affect the growth of a plant
Explanation:
Gene expression is the way by which the genes of an organism instructs the production of proteins, which are responsible for the organism's phenotype. However, the trait or characteristics possessed by organisms are not strictly or 100% dependent on the genotypic factors but also on the environmental factors.
Environmental factors are the biotic (living) and abiotic (non-living) factors that affect organisms development and growth. An example is how the amount of sun, water, and nutrients, which are all environmental factors, affect the growth of a plant. Growth in plant, therefore, affects gene expression.

#1
Possibly one of the most evolved sharks today are hammerhead sharks. They have an advanced sensory system and a body shape that has adapted to hunt specific prey
#2
Sharks may be one of the most important species on Earth. They have been maintaining our oceans for over 400 millions years.
#3
Sharks have evolved and changed much over millions of years. However many sharks today still share some of the features as sharks from millions of years ago.
#4
Sharks have been in our oceans for over 400 million years. Some of the earliest sharks were discovered dating back to the Devonian age.
#5
Sharks have survived five massive planet extinction events. These extinction events killed most life on earth and the last one around 65 million yeas ago killed the dinosaurs.
#6
There are over 500 species of shark.
#7
It is believed that each whale shark's pattern is unique, like a human's fingerprint.
#8
Sharks do not have bones. Instead, they have cartilage, that's what makes up human noses and ears
#9
According to the Smit.hsonian, there are over 500 known shark species, though many are endangered or declining due to various factors like overfishing.
#10
Your odds of getting attacked and killed by a shark are 1 in 3,748,067. In a lifetime, you are more likely to die from fireworks or lightning. Whereas over 100 million sharks are killed every year by humans.
#11
Whale sharks are the world’s biggest fish.
#12
Sharks mature slowly and reach reproductive age anywhere from 12 to 15 years.
#13
Hammerhead sharks' eyes are on the sides of their heads, so they have nearly a 360-degree sight line. Their panoramic view of the undersea world is inhibited by two blind spots, one in front of the snout and the other directly behind the head.
#14
Sharks predate the dinosaurs by 200 million years.
#15
Great whites can detect one drop of blood in 25 gal (100 L) of water and can sense even tiny amounts of blood in the water up to 3 mi (5 km) away.
