Question

which phenomenon would she hypothesize accounts for the pattern she sees?
○ independent assortment
○ cytokinesis
○ crossing - over
○ respiration

Explanation:

Independent assortment is the random distribution of homologous chromosomes during meiosis, which can lead to new combinations of genes. Cytokinesis is the division of the cytoplasm. Crossing - over is the exchange of genetic material between homologous chromosomes during meiosis, creating genetic variation. Respiration is the process of obtaining energy from food. If she is seeing a pattern related to genetic variation in offspring, crossing - over is a likely cause as it directly changes the genetic makeup of gametes.

Answer:

crossing - over
