In pea plants, plant height is controlled by a single autosomal dominant gene. tall plants (h) are dominant to short plants (h). in a cross of two tall heterozygous plants, which phenotype ratio is expected from the resulting offspring?

Dominant allele is H

Recessive allele is h

The heterozygous plant is Hh and its phenotype is a tall plant.

If we cross two heterozygous

Parents: Hh  x  Hh

F1 generation: HH  Hh  Hh  hh

Phenotype ratio is 3:1 (tall plants : short plants)

HH and Hh are for tall plants 

hh is for short plants

false because ozone (o3) depletion does not cause global warming, but both of these environmental problems have a common cause: human activities that release pollutants into the atmosphere altering it.

global warming is caused primarily by putting too much carbon dioxide into the atmosphere when coal, oil, and natural gas are burned to generate electricity or to run our cars.

explanation:

the answer is c.) there is a warm front in region a and a stationary front in region b.
