Elizabeth · Answer 1

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
