Between the new and full Moon, the amount of Moon we see grows — or waxes from its right side toward its left side. As it passes the full Moon stage, the amount of illumination decreases — or wanes — from right to left. ... No matter where on Earth an observer is, however, the phases of the Moon occur at the same time.
Crossing over does not prevent homologous chromosomes from separating during meiosis, hence, the statement is false.
CROSSING OVER:
- Crossing over is the process whereby non-sister chromatids 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 homologous chromosomes 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.
