- c The diploid cell produced by the union of haploid gametes during fertilization; a fertilized egg
- d The X-shaped, microscopically visible region where crossing over has occurred earlier in prophase I between homologous nonsister chromatids. they become visible after synapsis ends, with the two homologs remaining associated due to sister chromatid cohesion.

5 True/False Questions
cytokinesis → The division of the cytoplasm to form two separate daughter cells immediately after mitosis, meiosis I, or meiosis II.
diploid → A cell containing only one set of chromosomes (n).
crossing over → The reciprocal exchange of genetic material between nonsister chromatids during prophase I of meiosis.
meiosis → A process of nuclear division in eukaryotic cells conventionally divided into five stages: prophase, prometaphase, metaphase, anaphase, and telophase. conserves chromosome number by allocating replicated chromosomes equally to each of the daughter nuclei.
alternation of generations → A life cycle in which there is both a multicellular diploid form, the sporophyte, and a multicellular haploid form, the gametophyte; characteristic of plants and some algae.
