Explanation:

Phototropism- a response to light stimulus that directs the stem to grow toward the light and roots to grow away from it.

ii. Gravitropism- Stems and leaves grow away from the force of gravity while roots grow toward it.

iii.Thigmotropism - growth in response to touch stimulus. The side of the stem in contact with the object grows slower than the side not in contact. This causes the vine to twist around the object.

Explain how genetic recombination or genetic diversity might occur in a population of

tigry1 [53]

Answer:

In eukaryotes, recombination during meiosis is facilitated by chromosomal crossover. The crossover process leads to offspring having different combinations of genes from those of their parents, and can occasionally produce new chimeric alleles. The shuffling of genes brought about by genetic recombination produces increased genetic variation.
