Question

1. * 7 points 2013 - q26 26 crossing - over between nonsister chromatids during meiosis is significant in heredity. this process most likely leads to an increase in which of the following? f the expression of dominant traits g number of gametes h the occurrence of polyploidy j genetic variation f g h j

Explanation:

Crossing - over between nonsister chromatids during meiosis exchanges genetic material. This exchange leads to new combinations of genes. Dominant traits' expression (F) is related to allele dominance, not crossing - over. The number of gametes (G) is mainly determined by the process of meiosis itself (e.g., number of divisions), not crossing - over. Polyploidy (H) is about having extra sets of chromosomes, not related to crossing - over. Genetic variation (J) is increased as new gene combinations are formed through crossing - over.

Answer:

J. Genetic variation
