In modern classification system, unicellular organisms that contain chloroplasts and a nucleus would be considered; a) annelids b) protists c) archaea d) chordates

b) protists: because Protists are a group made up of protozoa, unicellular algae, and slime molds.and they have  chloroplasts in their cells

the answer would be 2, if crossing over doesn’t occur 2 out of 4 of the daughter cells will have that allele.

hope this : )

not sure if this is what you'r looking for nnew= nold
