Answer: The trait is recessive. the parents of A were both carriers

Explanation: The correct answer should be the trait is recessive.

Since we can only see A mothers tree and she is not affected by the trait she is a carrier.

Unfortuately, the tree does not show her father's side of the tree so we can only "assume" based on the options that he also is a carrier of the trait.

So answer it will be "The trait is recessive. the parents of A were both carriers"

san4es73 [151]

Photosynthetic lamellae

The endosymbiosis theory suggested that these cyanobacteria were engulfed by the eukaryotes and the cyanobacteria get transformed into the chloroplast.  

The region of the chloroplast that was formed in the cyanobacteria before the endosymbiosis happened was the photosynthetic lamellae which contained the chlorophyll molecule and thus is the correct answer.

Thus, Photosynthetic lamellae are the correct answer.
