Crossing over does not prevent homologouschromosomes from separating during meiosis, hence, the statement is false.
CROSSING OVER:
Crossing over is the process whereby non-sisterchromatids of homologous chromosomes exchange their genetic materials.
Crossing over occurs specifically during the prophase I stage of meiosis I. Via this process, genetic diversity is likely to occur in the daughter cells.
Crossing over only assures that genes of homologouschromosomes are recombined, it does not stop them from separating in the Anaphase stage.
Therefore, crossing over does not prevent homologous chromosomes from separating during meiosis, hence, the statement is false.
I think its because so the plants can absorb more nutrients from the soil while being sturdy and wide so when the plant gets snowed on it doesn't break<span />
