Aphenotype that results from a dominant allele must have at least dominant allele(s) present in the parent(s).

One dominant allele

Explanation:

Two alleles are needed in any one locus, and they can either be dominant or recessive. Since a dominant allele will hide the expression of the recessive allele, only one dominant allele is needed in the parents. In other words, one parent must contribute a dominant allele and the other parent can contribute either a dominant or a recessive allele. The resulting phenotype will have the dominant phenotype in all cases.

oxidation

explanation:

answer

the overall balanced equation

6co2 + 6h2o > c6h12o6 + 6o2

sunlight energy

where: co2 = carbon dioxide

h2o = water

light energy is required

c6h12o6 = glucose

o2 = oxygen
