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

These are composite plants consisting of blue-green algae within the mycelial mass of fungus. The algae are provided with a means of attachment.

Members of Chondrichthyes are thought to be descended from fishes that had ________.
ella [17]

The correct answer is B. A bony skeleton

Explanation:

In biology, Chondrichthyes are mainly marine jawed fishes that have cartilage skeletons rather than bone skeletons and also they have paired fins, this includes animals such as rays and sharks. In terms of origin, it is believed this type of fishes are mainly linked to placoderms that were a type of primitive fish that lived during the Devonian period that had a body skeleton as they were covered by hard structures called plates made of bone. Because of this, it is believed this structures evolved into less rigid ones made of cartilage although both the primitive fish and modern Chondrictyles share features such as the structure of jaws. Therefore, Chondrictyles descended from fishes that had a bony skeleton.
