Chromosomes in onion cells are typically longer and have visible constrictions called centromeres, giving a beaded appearance. On the other hand, whitefish chromosomes are usually shorter and more rod-shaped without distinct centromeres. Additionally, onion chromosomes are usually larger in size compared to whitefish chromosomes.

Compare any differences in the appearance of genes on chromosomes in gamete cells when crossing over occurs and when it does not occur?
When crossing over occurs during meiosis, the genes on homologous chromosomes can exchange segments, leading to genetic recombination and variations in offspring. This results in a shuffled arrangement of genes on the chromosomes of gamete cells. In contrast, when crossing over does not occur, the genes on homologous chromosomes remain in their original positions, resulting in no genetic recombination and less variation in offspring.
How does the number of chromosomes in a zygote compare with the number of chromosomes in a body cell?
A zygote typically has a full set of chromosomes, with one set from each parent, so it has a diploid number of chromosomes. In contrast, body cells are also diploid, containing the same number of chromosomes as the zygote.
Which of the following do cladistic taxonomists not compare when hypothesizing evolutionary relationships among organisms?
Cladistic taxonomists do not usually compare similarities in overall resemblance or appearance when hypothesizing evolutionary relationships among organisms. Instead, they focus on shared derived characteristics, or synapomorphies, to determine evolutionary relationships.
How does the number of chromosomes in metaphase of mitosis compare to the number of duplicated chromosomes in metaphase 2 of meiosis?
In metaphase of mitosis, the number of chromosomes is equal to the number of duplicated chromosomes. However, in metaphase 2 of meiosis, the number of chromosomes is half that of the duplicated chromosomes, since meiosis involves two rounds of cell division to produce haploid cells.
How do you chromosomes at end of meiosis i compare with the chromosomes at end of meiosis ii?
At the end of meiosis I, the chromosomes are duplicated (sister chromatids) and homologous chromosomes separate. At the end of meiosis II, the sister chromatids separate, resulting in four haploid daughter cells each with a single set of chromosomes. Meiosis II is similar to mitosis in terms of chromosome behavior as the sister chromatids separate.

The term "contrast" might be applied to the idea as black and white, when held up to compare or "contrast" them, present with about as "opposite" an appearance as is possible.
