Answer:
Dark colour.
Explanation:
Dark fur color seems to have the greatest selective advantage because of their hard physical body which occurs due to extreme environmental conditions. The dark colour of mice occurs due to the high intensity of sunlight which increases melanin in their skin. These dark colour mice pass through a very hard and extreme environmental conditions so that's why Dark fur color seems to have the greatest selective advantage.
You can determine the genotype of Maria and Juanita, even though you did not test their DNA is by looking at the traits of their parents. If they have other siblings, the ratio of the traits can give the actual genotype of their parents which in turn, can help determine the genotype of Maria and Juanita. This is assuming that the genotype in question corresponds to an observable physical trait.
Adding up the percentages given in the question above,
60% + 17% + 17% + 6%
will give us a hundred percent. Since all parts are being represented in the breakdown of percentages, the scientist may present the % composition in a pie graph.
The change from a high to a low pitch is a phenomenon known as the Doppler Effect or the Doppler shift. Sounds come in waves and are known as sound waves.
The Doppler Shift or effect is relevant to the location of the person who is hearing the sound. When a person is moving closer to the source of the sound, the wavelengths become shorter and they become low pitch; but when the person moves away from the source of the sound, the wavelengths become longer and become high-pitched.
