As a matter of terminology, albino guinea pig actually refers to a white fur guinea pig, whose genotype is homozygous recessive (bb).
If it crossed with a black fur guinea pig and gave 5 black fur offsprings, there is a good chance that the black fur parent is homozygous dominant (BB).
The Punnett square would be as follows:
B B
b Bb Bb
b Bb Bb
So they are all heterozygous black fur offsprings.
However, it is not impossible that the black fur parent be heterozygous, namely
B b
b Bb bb
b Bb bb
Giving a 50% chance on each colour. Thus it is possible (with probability 1/32) that all five offsprings are heterozygous black fur if one of the parents was heterozygous.
In the second case, a homozygous recessive and a homozygous dominant parent will never give a white offspring. So it is sure that the black fur parent is heterozygous, with the following Punnett square:
B b
b Bb bb
b Bb bb
With a 50% probability for each of Bb (black fur) and bb (white fur).
the distribution 4,3 demonstrates this perfectly.
Answer:
b. Scientists are interested in incorporating knowledge of how dolphins accurately transmit and receive information into the design of their tsunami detection networks. The scientists will probably want to investigate if there are any impacts of these networks on dolphins in the area.
Explanation:
Scientists want to study communication between dolphins because these animals are able to establish efficient communication with each other even over long distances. With the knowledge of this communication, scientists can incorporate similar factors into their tsunami information transmission system, so it will be easier to accurately transmit and receive information in the design of their tsunami detection networks.
However, it is necessary for scientists to include in the study, the possible impacts that this system of transmitting information about tsunamis can have on the dolphin population.
In summary, we can say that scientists are interested in incorporating knowledge of how dolphins transmit and receive information accurately in the design of their tsunami detection networks. However, scientists must investigate whether there is any impact of these nets on dolphins in the region.
Answer:
A
Explanation:
The relative distance between two consecutive feild lines is inversely proportional to the strength of the magnetic field. Since we observe that in region B (near the poles), the magnetic field lines are stacked together, while in region A, they have considerable perpendicular distance between them, which makes A weaker.
