Answer:
2/3 of the progeny would be green
Explanation:
Lethal alleles means that their presence result in death of the organism
Assuming this Lethal allele is recessive --> a
This way, if there is AA or Aa the plant will survive, otherwise if there is aa the plant will not survive
Than, assuming AA is a progeny white and Aa is green
Aa x Aa
2/3 Aa - Green
1/3 - White
1/3 - plant will not survive
Crossing 2 green progeny with each other
Aa x Aa
2/3 - Green
An arid environment is characterized by hot and dry climatic conditions. Plants and animals are adapted to survive in this harsh conditions. Rainfall is minimal to intermittent.
In arid environment, the climatic weathering is very slow because of no to minimal rainfall.
Mechanical or physical weathering most common in an arid environment is THERMAL WEATHERING due to constant increase in temperature.
