Ethanol was used as a blank to factor <u>the amount</u> of light absorbed by <u>the solvent</u> in the ethanol-chlorophyll solution.

By using a blank, the spectrophotometer is calibrated to zero, prior to measuring the chlorophyll solution. This "subtracts" the light absorption of the ethanol so that only the chlorophyll light absorption will be measured.

JulsSmile [24]

Answer:

They are co-dominance and incomplete dominance.

<h2 />

Explanation:

Co-dominance occurs when both alleles in a heterozygous genotype for a trait are both equally expressed. An example is the human AB blood group, in which both the A and B alleles are equally expressed.

Incomplete dominance occurs when the heterozygous genotype for a trait is expressed as a blend. An example is blue feather color in chickens, in which a black allele and white allele together are expressed as blue feather color.
