Answer:
D. A, B, AB, or O
Explanation:
We can start by visualizing all the possible genotypes of the offspring by drawing a Punnett square, which is a visual representation of the different possible combinations of alleles:
Individual 1 = AO, Individual 2 = BO
A O
B AB BO
O AO OO
Here we can see that there are 4 possible genotypes: AB, BO, AO and OO based on the alleles of the parents. Now we can match the genotypes to phenotypes to answer the question:
A and B are codominant, meaning that both will be expressed equally if both are present. Therefore the genotype AB will result in an AB phenotype.
Next, since A and B are both dominant over O, they are the alleles that will be expressed in the phenotype if paired with an O. This means that the genotype AO will result in an A phenotype, and likewise, genotype BO will result in phenotype B.
Finally in the genotype OO, although O is a recessive allele, there are no dominant alleles here to mask them, therefore O is expressed in the phenotype.
Hence, from the genotypes AO and BO, the possible offspring genotypes are AB, BO, AO and OO, translating to the possible phenotypes: A, B, AB or O.
Hope this helped!
Two examples of related organisms are dinosaurs/chickens, and the megalodon/the great white shark.
<h3>How have organisms evolved?</h3>
Life emerged on our planet 3.7 billion years ago, and since then organisms have evolved or changed over time this includes:
- The appearance of more complex organisms, which is the result of natural selection.
- The diversification of organisms.
- The extinction or disappearance of species.
This has caused all organisms that exist today to be related to other organisms of the past. Let's examine two examples.
<h3>Dinosaurs and chickens: </h3>
According to scientific research, birds evolved from dinosaurs. Indeed, it has been determined birds started with theropods, which were a specific group of dinosaurs.
This means modern birds including chickens are related to this group of dinosaurs, even if overtime birds have evolved a lot and they might not seem to be very similar to dinosaurs.
<h3>The megalodon and the great white shark:</h3>
These two species of shark likely share a common ancestor and due to this, both species have many similarities such as the shape of their teeth. However, megalodons are extinct, while great white sharks still exist today.

There would be no energy.
Mitochondria break down food and convert it to ATP for the body to use.
If mitochondria were absent, eating food would be useless, it would not provide nutrition.
The value of Q is 0.44 if 20 organisms of 100 organisms are green.
Explanation:
Data given:
alleles for the color of eyes of fly:
blue allele = dominant represented by P
green allele = recessive, represented by Q
total number of organism = 100
number of recessive trait organism, 
= 20
Q =?
The allele frequency of the green eye is calculated as:
= 
= 0.2
q = 
q = 0.44
0.44 is the frequency of Q allele in the population.
Q is the homozygous recessive alleles in the population and its value is 0.44.
