Well firstly, alleles are different versions of genes. A dominant allele will show it's trait regardless of if the organism only has one copy of the allele (heterozygous). A recessive allele will show the effect only if two copies of the allele are present (homozygous)

If the two alleles are different, the plant is said to be a hybrid or heterogeneous for that traits. As Mendel noted, when both alleles are present, one allele masks or hides the other. The stronger allele is said to dominant, and the weaker allele that is masksed is said to be recessive.

Leno4ka [110]

Answer:

Higher Photosynthesis, lower carbondioxide concentration in the atmosphere and vice versa.

Explanation:

Photosynthesis is greatly responsible for the fluctuation of carbondioxide concentration in the atmosphere because photosynthesis is the process where carbondioxide gas is used in large amount. If the vegetation occurs higher in the season, decrease will occur in the carbondioxide concentration of the atmosphere while on the other hand, if the less vegetation occur then there is higher amount of carbondioxide concentration in the atmosphere.
