Hope this help
The f1 progeny all are checkered It is an example of codominance.
In genetics, codominance refers to a kind of inheritance inside which two variants (alleles) with same gene are activated separately to produce distinct features in a person. Codominance may be seen in spotted cows and plants with petals of two distinct hues.
Codominance can also be seen in less obvious features such as type of blood. Both the A and B blood type alleles can be produced simultaneously at the same time, producing in type AB blood. Codominance, as distinguished to partial domination, occurs when both parents' traits are manifested in the same child organism.
Codominance is a widespread phenomena that is likely to be a major driver of community composition, ecosystem function, and both community and ecosystem stability. While researching polygenetic features and their inheritance, Gregor Mendel identified the phenomena of codominance.

Answer:
Water molecules are isolated in its vapour form.
Explanation:
Water has polar molecules in all its form but when water becomes vapour its molecules became isolated. Their bond angles were bent at 105 degree. All the negative charges that is produced in water’s boiling point started concentrating the oxygen molecules and the positives were concentrating the hydrogen molecules.
However, the protons were partially positively charged. The electrons become 10 times greater near the oxygen than hydrogen.

carbon dioxide CO2

plants need it to produce
