What occurs in crossing over:
1. Recombination
2. Mutation
3. Independent assortment
4. None
Amount of cellular DNA increases during:
1. | Cytokinesis | 2. | Fertilisation |
3. | Mutation | 4. | Respiration |
Crossing over that results in genetic recombination in higher organisms occurs between:
1. Non-sister chromatids of a bivalent
2. Two daughter nuclei
3. Two different bivalents
4. Sister chromatids of a bivalent
