Explanation:
Even though the technology does not exist to travel into all of Earth’s layers, scientists can still learn a great deal about Earth’s structure through seismic waves. Seismic waves are vibrations in the earth that transmit energy and occur during seismic activity such as earthquakes, volcanic eruptions, and even man-made explosions. There are two types of seismic waves, primary waves and secondary waves. Primary waves, also known as P waves or pressure waves, are longitudinal compression waves similar to the motion of a slinky (SF Fig. 7.1 A). Secondary waves, or S waves, are slower than P waves. The motion of secondary waves is perpendicular to the direction of the wave travel, similar to the motion of vigorously shaking a rope
Individual with genotype AaBBCC has the dark skin colour.
Explanation:
The skin colour is a polygenetic trait i.e two or more genes control the particular characteristic in an individual.
The amount of gene in the individual in such cases would determine the skin tone.
It is given that dominant alleles are responsible for darkest colour of the skin in the example. We could see that the genotype AaBBCC has maximum dominant alleles which makes us to deduce that individual with this genotype will have dark skin phenotype.
This quantitative occurrence of alleles in the individual decides its skin colour and variations in it.
The genes are independent of each other but have an additive effect on the phenotype like skin colour.
