Crossing over allows the reassortment of parental combinations of alleles.Group startsTrue or False

True

Crossing over, also known as recombination, is a crucial process that occurs during meiosis when homologous chromosomes exchange segments of their genetic material. This event contributes to genetic diversity in sexually reproducing organisms. By allowing the swapping of alleles between maternal and paternal chromosomes, crossing over creates new allele combinations that are not found in the parents. As a result, the offspring can inherit different combinations of alleles, leading to variations in traits and characteristics. This genetic reassortment is fundamental for evolution and adaptation, as it increases the variability of genotypes within a population, enabling better responses to environmental changes and selection pressures.

In summary, crossing over is essential for the reassortment of parental combination of alleles, and thus the statement is true.
