Suppose a gene has two alleles, one of which is dominant over the other. An individual whose genotype is for the recessive allel
Trava [24]

Answer:

This question is incomplete, the options are:

A. Two copies of the allele that determines phenotype whenever the allele is present

B. Two copies of the allele whose effect is hidden unless the other allele is absent

C. One copy of the allele that determines phenotype when present and one copy of the other allele

D. One copy of each of two alleles that both contribute equally to determining phenotype

The answer is B.

Explanation:

According to Gregor Mendel, a Gene comes in two alternative forms called ALLELES. One allele called the DOMINANT ALLELE is capable of masking the phenotypic expression of the other called the RECESSIVE ALLELE. The dominant allele will always express itself whenever it is present. However, a recessive trait will only be expressed when two alleles for recessiveness occur in the gene.

An individual whose genotype is for the recessive allele will have two copies of the allele whose effect is hidden unless the other allele is absent. This means that in that particular gene, the two present alleles will be recessive alleles.

Why are all of the pigments not visible in a typical leaf?
igor_vitrenko [27]

The set of Wavelength is absorbed by pigment. So in a typical leaf some pigment can’t be visible.

Explanation:

There are mainly three types of key pigments in photosynthesis.  These three key pigments are Chlorophyll a, Chlorophyll b, and β-carotene. Those set of wavelengths which is not absorbed by pigment and finally it is reflected and that reflected light is what we see as a color.

The reason behind color of plant looking green because it contains huge amount of chlorophyll a and b molecule. It reflects the green light.
