Cell division happens twice during meiosis. One starting cell can produce for gametes (eggs or sperm.) In each round of division, cells go through four phases called prophase, metaphase, anaphase, and telophase.
prophase During prophase the chromosomes become visible as paired chromatids and the nuclear envelope disappears. This phase includes reduction division, which is where the number of chromosomes is decreased from 46 (diploid) to 23 (haploid.)
metaphase This is where the 23 remaining chromosomes become attached to the spindle fibers.
anaphase During this phase, the chromosomes move away from each other to one or the other pole of the spindle fiber.
telophase In which the chromatids or chromosomes move to opposite ends of the cell and two nuclei are formed.
interphase This is a resting period.

Answer:
To complete the question: a diploid organism has four pairs of chromosomes what proportion of gametes would be expected to contain some chromosomes from both parental and maternal origin? assume that there is no crossing over
Answer: 7/8
Explanation:
A diploid organism with four pairs of chromosomes...
Assume that the organism receives chromosomes A, B, C and D from the female parent and A', B', C' and D' from the male parent.
Proportion of gametes from patterns origin is the same as that of matters origin, this we have:
(1/2)^4 = 1/16 where 4 reps the number of possibilities, 1/2 rep the chance
Thus, the proportion of gametes expected to contain some chromosomes from both parental and maternal origin would be
(1 - (1/16 + 1/16)) = 14/16 = 7/8
