The F1 offspring of Mendel's classic pea plant crosses always looked like one of the two parental varieties because he crossed a homozygous dominant plant with a homozygous recessive plant so each plant received one recessive allele and one dominant allele. All of the plants looked like one plant because the dominant allele overshadowed the recessive allele
I am pretty sure it is something related to space

The answer is the
population size. The chance has a role
in determining whether a given individual survives and reproduces and the
alleles in the offspring are a sample of those in the parents. it is the change
in the frequency of an existing gene variant (allele) in a population due to
random sampling of organisms. Genetic Drift or another term for allelic drift
or the Sewall Wright effect.
Evaporation. Transpiration and photosynthesis deal with plants, living things. Sweating with humans, living things. Evaporation does not, therefore leaving it the only option left.
