Processes that do not require oxygen are called

Anaerobic process

Cellular respiration requires oxygen and a food molecule such as glucose, and it gives off carbon dioxide, water, and energy. Pathways of cellular respiration that require oxygen are said to be aerobic. Glycolysis does not require oxygen, so it can quickly supply energy to cells when oxygen is unavailable.

this would be a math

this is true, assuming that the allele is completely recessive and incomplete dominance is not a factor.
