The parental phenotype is the mother's free earlobes (Ff) and the father's nonfree earlobes (ff).

<h3>What genotype and phenotype?</h3>

The genotype refers to the information present in an individual's genome. Unlike the phenotype, it is not observable and rarely changes. The phenotype, in turn, depends on a combination between our genotype and the environment and can be defined as the observable characteristics of an individual.

With this information, we can conclude that the parental phenotype is the mother's free earlobes (Ff) and the father's nonfree earlobes (ff).

s2008m [1.1K]

<u>Answer:</u>

The correct answer option is B. Green wavelengths are the least used in photosynthesis.

Plants have a pigment in them called as chlorophyll. This chlorophyll is able to absorb only certain wavelengths of the light within the light spectrum.

From that visible light spectrum, chlorophyll is only able to absorb light of red and blue wavelength. The green light is not absorbed by the by chlorophyll as it is reflected back.

Therefore, this reflection of green light makes the leaves to appear green.
