Matching. In each space at left, place the number of the closely associated statement from the list at right. Each term is correct only once ( 0.5 mark each)
Terms: Statements:
2 Meiosis
4 Synapsis
8 Homologous chromosomes
1 Synaptonemal complex
7 Karyotype
3 Tetrads
5 Early Prophase I
6 Chiasma 1. A network of proteins that holds non-sister chromatids together during meiosis one
2.is a reduction division because the outcome is a reduction in chromosome number
3. Structure formed by synapsed homologous chromosomes during prophase of meiosis I
4.Crossing over during this time
5. Synapsis forms, also the spindle apparatus forms and nuclear envelope disappears
6. The X-shaped structure formed by crossing over between nonsister chromatids
7. Distinctive appearance of all of the chromosomes in individuals (ex.length, banding patterns)
8. Chromosomes similar in size, shape, and gene content
