(number 15)which phase of mitosis during growth and development demonstrates the communication and exchange of genetic information by aligning chromosomes in the middle of the cell?

The correct answer is: 2.metaphase.

Mitosis is a process of cell division and it is separatd into phases.

•Interphase-DNA replication (two identical full sets of chromosomes),

•Prophase-chromosomes composed of two sister chromatids with identical genetic information,

•Metaphase- chromosomes line up along the centre of the cell,

•Anaphase- chromatids are pulled apart by the mitotic spindle (one chromatid to one pole and the other chromatid to the opposite pole),

•Telophase- a full set of chromosomes at each pole of the cell.

the offspring would all be white. if the parents are both white flowers then they have the genotype rr, which when crossed results in an all white punnet square.
